This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Here's ## why we pick this rather obscure method: ## - Don't want to use -MD because we'd like the dependencies to end ## up in a subdir. Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say).

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

 * mod_extforward.c for lighttpd, by comman.kang  gmail  com
 *                  extended, modified by Lionel Elie Mamane (LEM), lionel  mamane  lu
 *                  support chained proxies by glen@delfi.ee, #1528
 *
 * Config example:
 *
 *       Trust proxy 10.0.0.232 and 10.0.0.232
 *       extforward.forwarder = ( "10.0.0.232" => "trust",
 *                                "10.0.0.233" => "trust" )
 *
 *       Trust all proxies  (NOT RECOMMENDED!)
 *       extforward.forwarder = ( "all" => "trust")
 *
 *       Note that "all" has precedence over specific entries,
 *       so "all except" setups will not work.
 *
 *       In case you have chained proxies, you can add all their IP's to the
 *       config. However "all" has effect only on connecting IP, as the
 *       X-Forwarded-For header can not be trusted.
 *
 * Note: The effect of this module is variable on $HTTP["remotip"] directives and
 *       other module's remote ip dependent actions.
 *  Things done by modules before we change the remoteip or after we reset it will match on the proxy's IP.
 *  Things done in between these two moments will match on the real client's IP.
 *  The moment things are done by a module depends on in which hook it does things and within the same hook
 *  on whether they are before/after us in the module loading order
 *  (order in the server.modules directive in the config file).
 *
 * Tested behaviours:
 *
 *  mod_access: Will match on the real client.
 *
 *  mod_accesslog:
 *   In order to see the "real" ip address in access log ,
 *   you'll have to load mod_extforward after mod_accesslog.
 *   like this:
 *
 *    server.modules  = (
 *       .....
 *       mod_accesslog,
 *       mod_extforward
 *    )
 *
 * Known issues:
 *      seems causing segfault with mod_ssl and $HTTP{"socket"} directives
 *      LEM 2006.05.26: Fixed segfault $SERVER["socket"] directive. Untested with SSL.
 *
 * ChangeLog:
 *     2005.12.19   Initial Version
 *     2005.12.19   fixed conflict with conditional directives
 *     2006.05.26   LEM: IPv6 support
 *     2006.05.26   LEM: Fix a segfault with $SERVER["socket"] directive.
 *     2006.05.26   LEM: Run at uri_raw time, as we don't need to see the URI
 *                       In this manner, we run before mod_access and $HTTP["remoteip"] directives work!
 *     2006.05.26   LEM: Clean config_cond cache of tests whose result we probably change.

/******************** From the file "msort.c" *******************************/
/*
** A generic merge-sort program.
**
** USAGE:
** Let "ptr" be a pointer to some structure which is at the head of
** a null-terminated list.  Then to sort the list call:
**
**     ptr = msort(ptr,&(ptr->next),cmpfnc);
**
** In the above, "cmpfnc" is a pointer to a function which compares
** two instances of the structure and returns an integer, as in
** strcmp.  The second argument is a pointer to the pointer to the
** second element of the linked list.  This address is used to compute
** the offset to the "next" field within the structure.  The offset to
** the "next" field must be constant for all structures in the list.
**
** The function returns a new pointer which is the head of the list
** after sorting.
**
** ALGORITHM:
** Merge-sort.

           An implementation of top-down splaying with sizes
             D. Sleator , January 1994.

  This extends top-down-splay.c to maintain a size field in each node.
  This is the number of nodes in the subtree rooted there.  This makes
  it possible to efficiently compute the rank of a key.  (The rank is
  the number of nodes to the left of the given key.)  It it also
  possible to quickly find the node of a given rank.  Both of these
  operations are illustrated in the code below.  The remainder of this
  introduction is taken from top-down-splay.c.

  "Splay trees", or "self-adjusting search trees" are a simple and
  efficient data structure for storing an ordered set.  The data
  structure consists of a binary tree, with no additional fields.  It
  allows searching, insertion, deletion, deletemin, deletemax,
  splitting, joining, and many other operations, all with amortized
  logarithmic performance.  Since the trees adapt to the sequence of
  requests, their performance on real access patterns is typically even
  better.  Splay trees are described in a number of texts and papers
  [1,2,3,4].

  The code here is adapted from simple top-down splay, at the bottom of
  page 669 of [2].  It can be obtained via anonymous ftp from
  spade.pc.cs.cmu.edu in directory /usr/sleator/public.

  The chief modification here is that the splay operation works even if the
  item being splayed is not in the tree, and even if the tree root of the
  tree is NULL.  So the line:

                              t = splay(i, t);

  causes it to search for item with key i in the tree rooted at t.  If it's
  there, it is splayed to the root.  If it isn't there, then the node put
  at the root is the last one before NULL that would have been reached in a
  normal binary search for i.  (It's a neighbor of i in the tree.)  This
  allows many other operations to be easily implemented, as shown below.

/* The next thing included is series of defines which control
** various aspects of the generated parser.
**    YYCODETYPE         is the data type used for storing terminal
**                       and nonterminal numbers.  "unsigned char" is
**                       used if there are fewer than 250 terminals
**                       and nonterminals.  "int" is used otherwise.
**    YYNOCODE           is a number of type YYCODETYPE which corresponds
**                       to no legal terminal or nonterminal number.  This
**                       number is used to fill in empty slots of the hash
**                       table.
**    YYFALLBACK         If defined, this indicates that one or more tokens
**                       have fall-back values which should be used if the
**                       original value of the token will not parse.
**    YYACTIONTYPE       is the data type used for storing terminal
**                       and nonterminal numbers.  "unsigned char" is
**                       used if there are fewer than 250 rules and
**                       states combined.  "int" is used otherwise.
**    ParseTOKENTYPE     is the data type used for minor tokens given
**                       directly to the parser from the tokenizer.
**    YYMINORTYPE        is the data type used for all minor tokens.
**                       This is typically a union of many types, one of
**                       which is ParseTOKENTYPE.  The entry in the union
**                       for base tokens is called "yy0".
**    YYSTACKDEPTH       is the maximum depth of the parser's stack.
**    ParseARG_SDECL     A static variable declaration for the %extra_argument
**    ParseARG_PDECL     A parameter declaration for the %extra_argument
**    ParseARG_STORE     Code to store %extra_argument into yypParser
**    ParseARG_FETCH     Code to extract %extra_argument from yypParser
**    YYNSTATE           the combined number of states.
**    YYNRULE            the number of rules in the grammar
**    YYERRORSYMBOL      is the code number of the error symbol.  If not
**                       defined, then do no error processing.

/* Next are that tables used to determine what action to take based on the
** current state and lookahead token.  These tables are used to implement
** functions that take a state number and lookahead value and return an
** action integer.
**
** Suppose the action integer is N.  Then the action is determined as
** follows
**
**   0 <= N < YYNSTATE                  Shift N.  That is, push the lookahead
**                                      token onto the stack and goto state N.
**
**   YYNSTATE <= N < YYNSTATE+YYNRULE   Reduce by rule N-YYNSTATE.
**
**   N == YYNSTATE+YYNRULE              A syntax error has occurred.
**
**   N == YYNSTATE+YYNRULE+1            The parser accepts its input.
**
**   N == YYNSTATE+YYNRULE+2            No such action.  Denotes unused
**                                      slots in the yy_action[] table.
**
** The action table is constructed as a single large table named yy_action[].
** Given state S and lookahead X, the action is computed as
**
**      yy_action[ yy_shift_ofst[S] + X ]
**
** If the index value yy_shift_ofst[S]+X is out of range or if the value
** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X or if yy_shift_ofst[S]
** is equal to YY_SHIFT_USE_DFLT, it means that the action is not in the table
** and that yy_default[S] should be used instead.
**
** The formula above is for computing the action when the lookahead is
** a terminal symbol.  If the lookahead is a non-terminal (as occurs after
** a reduce action) then the yy_reduce_ofst[] array is used in place of
** the yy_shift_ofst[] array and YY_REDUCE_USE_DFLT is used in place of
** YY_SHIFT_USE_DFLT.
**
** The following are the tables generated in this section:
**
**  yy_action[]        A single table containing all actions.
**  yy_lookahead[]     A table containing the lookahead for each entry in
**                     yy_action.  Used to detect hash collisions.
**  yy_shift_ofst[]    For each state, the offset into yy_action for
**                     shifting terminals.
**  yy_reduce_ofst[]   For each state, the offset into yy_action for
**                     shifting non-terminals after a reduce.
**  yy_default[]       Default action for each state.

/**
 *
 * the proxy module is based on the fastcgi module
 *
 * 28.06.2004 Jan Kneschke     The first release
 * 01.07.2004 Evgeny Rodichev  Several bugfixes and cleanups
 *            - co-ordinate up- and downstream flows correctly (proxy_demux_response
 *              and proxy_handle_fdevent)
 *            - correctly transfer upstream http_response_status;
 *            - some unused structures removed.
 *
 * TODO:      - delay upstream read if write_queue is too large
 *              (to prevent memory eating, like in apache). Shoud be
 *              configurable).
 *            - persistent connection with upstream servers
 *            - HTTP/1.1

/*
 * This was 'borrowed' from tcpdump.
 *
 *
 * This is fun.
 *
 * In older BSD systems, socket addresses were fixed-length, and
 * "sizeof (struct sockaddr)" gave the size of the structure.
 * All addresses fit within a "struct sockaddr".
 *
 * In newer BSD systems, the socket address is variable-length, and
 * there's an "sa_len" field giving the length of the structure;
 * this allows socket addresses to be longer than 2 bytes of family
 * and 14 bytes of data.
 *
 * Some commercial UNIXes use the old BSD scheme, some use the RFC 2553
 * variant of the old BSD scheme (with "struct sockaddr_storage" rather
 * than "struct sockaddr"), and some use the new BSD scheme.
 *
 * Some versions of GNU libc use neither scheme, but has an "SA_LEN()"
 * macro that determines the size based on the address family.  Other
 * versions don't have "SA_LEN()" (as it was in drafts of RFC 2553
 * but not in the final version).  On the latter systems, we explicitly
 * check the AF_ type to determine the length; we assume that on
 * all those systems we have "struct sockaddr_storage".

**                       original value of the token will not parse.
**    YYACTIONTYPE       is the data type used for storing terminal
**                       and nonterminal numbers.  "unsigned char" is
**                       used if there are fewer than 250 rules and
**                       states combined.  "int" is used otherwise.
**    ssiexprparserTOKENTYPE     is the data type used for minor tokens given
**                       directly to the parser from the tokenizer.
**    YYMINORTYPE        is the data type used for all minor tokens.
**                       This is typically a union of many types, one of
**                       which is ssiexprparserTOKENTYPE.  The entry in the union
**                       for base tokens is called "yy0".
**    YYSTACKDEPTH       is the maximum depth of the parser's stack.
**    ssiexprparserARG_SDECL     A static variable declaration for the %extra_argument
**    ssiexprparserARG_PDECL     A parameter declaration for the %extra_argument
**    ssiexprparserARG_STORE     Code to store %extra_argument into yypParser
**    ssiexprparserARG_FETCH     Code to extract %extra_argument from yypParser
**    YYNSTATE           the combined number of states.
**    YYNRULE            the number of rules in the grammar
**    YYERRORSYMBOL      is the code number of the error symbol.  If not
**                       defined, then do no error processing.

/* Next are that tables used to determine what action to take based on the
** current state and lookahead token.  These tables are used to implement
** functions that take a state number and lookahead value and return an
** action integer.
**
** Suppose the action integer is N.  Then the action is determined as
** follows
**
**   0 <= N < YYNSTATE                  Shift N.  That is, push the lookahead
**                                      token onto the stack and goto state N.
**
**   YYNSTATE <= N < YYNSTATE+YYNRULE   Reduce by rule N-YYNSTATE.
**
**   N == YYNSTATE+YYNRULE              A syntax error has occurred.
**
**   N == YYNSTATE+YYNRULE+1            The parser accepts its input.
**
**   N == YYNSTATE+YYNRULE+2            No such action.  Denotes unused
**                                      slots in the yy_action[] table.
**
** The action table is constructed as a single large table named yy_action[].
** Given state S and lookahead X, the action is computed as
**
**      yy_action[ yy_shift_ofst[S] + X ]
**
** If the index value yy_shift_ofst[S]+X is out of range or if the value
** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X or if yy_shift_ofst[S]
** is equal to YY_SHIFT_USE_DFLT, it means that the action is not in the table
** and that yy_default[S] should be used instead.
**
** The formula above is for computing the action when the lookahead is
** a terminal symbol.  If the lookahead is a non-terminal (as occurs after
** a reduce action) then the yy_reduce_ofst[] array is used in place of
** the yy_shift_ofst[] array and YY_REDUCE_USE_DFLT is used in place of
** YY_SHIFT_USE_DFLT.
**
** The following are the tables generated in this section:
**
**  yy_action[]        A single table containing all actions.
**  yy_lookahead[]     A table containing the lookahead for each entry in
**                     yy_action.  Used to detect hash collisions.
**  yy_shift_ofst[]    For each state, the offset into yy_action for
**                     shifting terminals.
**  yy_reduce_ofst[]   For each state, the offset into yy_action for
**                     shifting non-terminals after a reduce.
**  yy_default[]       Default action for each state.

##
##  Modules to load
## -----------------
##
## at least mod_access and mod_accesslog should be loaded
## all other module should only be loaded if really neccesary
##
## - saves some time
## - saves memory
##
## the default module set contains:
##
## "mod_indexfile", "mod_dirlisting", "mod_staticfile"
##
## you dont have to include those modules in your list
##
## Modules, which are pulled in via conf.d/*.conf
##
## NOTE: the order of modules is important.
##
## - mod_accesslog     -> conf.d/access_log.conf
## - mod_compress      -> conf.d/compress.conf
## - mod_status        -> conf.d/status.conf
## - mod_webdav        -> conf.d/webdav.conf
## - mod_cml           -> conf.d/cml.conf
## - mod_evhost        -> conf.d/evhost.conf
## - mod_simple_vhost  -> conf.d/simple_vhost.conf
## - mod_mysql_vhost   -> conf.d/mysql_vhost.conf
## - mod_trigger_b4_dl -> conf.d/trigger_b4_dl.conf
## - mod_userdir       -> conf.d/userdir.conf
## - mod_rrdtool       -> conf.d/rrdtool.conf
## - mod_ssi           -> conf.d/ssi.conf
## - mod_cgi           -> conf.d/cgi.conf
## - mod_scgi          -> conf.d/scgi.conf
## - mod_fastcgi       -> conf.d/fastcgi.conf
## - mod_proxy         -> conf.d/proxy.conf
## - mod_secdownload   -> conf.d/secdownload.conf
## - mod_expire        -> conf.d/expire.conf
##

##  FastCGI Module 
## --------------- 
##
## http://www.lighttpd.net/documentation/scgi.html
##
server.modules += ( "mod_scgi" )

##
## Ruby on Rails Example
##
## Normally you only run one Rails application on one vhost.
##
#$HTTP["host"] == "rails1.example.com" {
#  server.document-root  = server_root + "/rails/someapp/public"
#  server.error-handler-404 = "/dispatch.fcgi"
#  scgi.server = ( ".scgi" =>
#    ("scgi-someapp" =>
#      ( "socket" => socket_dir + "/someapp-scgi.socket",
#        "bin-path" => server_root + "/rails/someapp/public/dispatch.scgi",
#        "bin-environment" => (
#              "RAILS_ENV" => "production",
#              "TMP" => home_dir + "/rails/someapp",
#        ),
#      )
#    )
#  )
#}

##
## 2nd Ruby on Rails Example
##
## This time we launch the rails application via scgi_rails externally. 
##
#$HTTP["host"] == "rails2.example.com" {
#  server.document-root  = server_root + "/rails/someapp/public"
#  server.error-handler-404 = "/dispatch.scgi"
#  scgi.server = ( ".scgi" =>
#    ( "scgi-tcp" =>
#      (
#        "host" => "127.0.0.1",
#        "port" => 9998,
#        "check-local" => "disable",
#      )
#    )
#  )
#}

## PHP Example
## For PHP don't forget to set cgi.fix_pathinfo = 1 in the php.ini.
##
## The number of php processes you will get can be easily calculated:
##
## num-procs = max-procs * ( 1 + PHP_FCGI_CHILDREN )
##
## for the php-num-procs example it means you will get 17*5 = 85 php
## processes. you always should need this high number for your very
## busy sites. And if you have a lot of RAM. :)

##  Tuning/Performance
## --------------------
##
## corresponding documentation:
## http://www.lighttpd.net/documentation/performance.html
##
## set the event-handler (read the performance section in the manual)
##
## possible options on linux are:
##
## select
## poll
## linux-sysepoll
##
## linux-sysepoll is recommended on kernel 2.6.
##
server.event-handler = "linux-sysepoll"

##
## The basic network interface for all platforms at the syscalls read()
## and write(). Every modern OS provides its own syscall to help network
## servers transfer files as fast as possible 
##
## linux-sendfile - is recommended for small files.
## writev         - is recommended for sending many large files
##
server.network-backend = "linux-sendfile"

##
## As lighttpd is a single-threaded server, its main resource limit is
## the number of file descriptors, which is set to 1024 by default (on
## most systems).
##
## If you are running a high-traffic site you might want to increase this
## limit by setting server.max-fds.
##
## Changing this setting requires root permissions on startup. see
## server.username/server.groupname.
##
## By default lighttpd would not change the operation system default.
## But setting it to 2048 is a better default for busy servers.
##
server.max-fds = 2048

##
## Stat() call caching.
##
## lighttpd can utilize FAM/Gamin to cache stat call.
##
## possible values are:
## disable, simple or fam.
##
server.stat-cache-engine = "simple"

##
## Fine tuning for the request handling
##
## max-connections == max-fds/2 (maybe /3)
## means the other file handles are used for fastcgi/files
##
server.max-connections = 1024

##
## How many seconds to keep a keep-alive connection open,
## until we consider it idle. 
##
## Default: 5
##
#server.max-keep-alive-idle = 5

##
## How many keep-alive requests until closing the connection.
##
## Default: 16
##
#server.max-keep-alive-requests = 16

##
## Maximum size of a request in kilobytes.
## By default it is unlimited (0).
##
## Uploads to your server cant be larger than this value.
##
#server.max-request-size = 0

##
## Time to read from a socket before we consider it idle.
##
## Default: 60
##
#server.max-read-idle = 60

##
## Time to write to a socket before we consider it idle.
##
## Default: 360
##
#server.max-write-idle = 360

##
##  Traffic Shaping 
## -----------------
##
## see /usr/share/doc/lighttpd/traffic-shaping.txt
##
## Values are in kilobyte per second.
##
## Keep in mind that a limit below 32kB/s might actually limit the
## traffic to 32kB/s. This is caused by the size of the TCP send
## buffer. 
##
## per server:
##
#server.kbytes-per-second = 128

##
## per connection:
##
#connection.kbytes-per-second = 32

##  SSL Support

##   ssl.pemfile = "/path/to/server.pem"
##
## The HTTPS protocol does not allow you to use name-based virtual
## hosting with SSL. If you want to run multiple SSL servers with
## one lighttpd instance you must use IP-based virtual hosting: ::
##

## This is enabled by default.
##
## IMPORTANT: this setting can only be used in the global scope.
## It does *not* work inside conditionals

##     # (Following SSL/TLS Deployment Best Practices 1.3 / 17 September 2013 from:
##     # https://www.ssllabs.com/projects/best-practices/index.html)
##     # - BEAST is considered mitigaed on client side now, and new weaknesses have been found in RC4,
##     #   so it is strongly advised to disable RC4 ciphers (HIGH doesn't include RC4)
##     # - It is recommended to disable 3DES too (although disabling RC4 and 3DES breaks IE6+8 on Windows XP,
##     #   so you might want to support 3DES for now - just remove the '!3DES' parts below).
##     # - The examples below prefer ciphersuites with "Forward Secrecy" (and ECDHE over DHE (alias EDH)), remove '+kEDH +kRSA'
##     #   if you don't want that.
##     # - SRP and PSK are not supported anyway, excluding those ('!kSRP !kPSK') just keeps the list smaller (easier to review)
##     # Check your cipher list with: openssl ciphers -v '...' (use single quotes as your shell won't like ! in double quotes)
##     #
##     # If you know you have RSA keys (standard), you can use:
##     ssl.cipher-list             = "aRSA+HIGH !3DES +kEDH +kRSA !kSRP !kPSK"
##     # The more generic version (without the restriction to RSA keys) is
##     # ssl.cipher-list           = "HIGH !aNULL !3DES +kEDH +kRSA !kSRP !kPSK"
##     #
##     # Make the server prefer the order of the server side cipher suite instead of the client suite.

.. contents:: Table of Contents

Description
===========

Simple assumption:

Every virtual host is in a directory below a base directory in a path that
is the same as the name of the vhost. Below this vhost path might be an
extra directory which is the document root of the vhost.

The document root for each vhost is built from three values:

- server-root
- hostname
- document-root

The complete document root is constructed either by ::

  server-root + hostname + document-root

or if this path does not exist by ::

  server-root + default-host + document-root

A small example should make this idea clear: ::

  /var/www/
  /var/www/logs/
  /var/www/servers/
  /var/www/servers/www.example.org/
  /var/www/servers/www.example.org/lib/

  /var/www/servers/mail.example.org/pages/

  simple-vhost.server-root = "/var/www/servers/"
  simple-vhost.default-host = "www.example.org"
  simple-vhost.document-root = "pages"

You can use symbolic links to map several hostnames to the same directory.

Conditionals vs. simple-vhost
-----------------------------

You have to keep in mind that conditionals and simple-vhost interfere
with one another. ::

  simple-vhost.server-root = "/var/www/servers/"
  simple-vhost.default-host = "www.example.org"
  simple-vhost.document-root = "pages"

  $HTTP["host"] == "news.example.org" {
    server.document-root = "/var/www/servers/news2.example.org/pages/"
  }

When ``news.example.org`` is requested, the ``server.document-root``
will be set to ``/var/www/servers/news2.example.org/pages/``, but
simple-vhost will overwrite it shortly afterwards.

If ``/var/www/servers/news.example.org/pages/`` exists, that will be
used. If not, ``/var/www/servers/www.example.org/pages/`` will be taken
because it is the default.

To use conditionals together with simple-vhost, you should do this: ::

  $HTTP["host"] !~ "^(news\.example\.org)$" {
    simple-vhost.server-root = "/var/www/servers/"
    simple-vhost.default-host = "www.example.org"
    simple-vhost.document-root = "pages"
  }

  $HTTP["host"] == "news.example.org" {
    server.document-root = "/var/www/servers/news2.example.org/pages/"
  }

It will enable simple vhosting for all hosts other than ``news.example.org``.

Options
=======

simple-vhost.server-root
  root of the virtual host

simple-vhost.default-host
  use this hostname if the requested hostname does not have its own directory

simple-vhost.document-root
  path below the vhost directory

Output Compression
==================

--------------------
Module: mod_compress
--------------------


.. meta::
  :keywords: lighttpd, compress

.. contents:: Table of Contents

Description
===========

Output compression reduces the network load and can improve the overall
throughput of the webserver. All major http-clients support compression by
announcing it in the Accept-Encoding header. This is used to negotiate the
most suitable compression method. We support deflate, gzip and bzip2.

deflate (RFC1950, RFC1951) and gzip (RFC1952) depend on zlib while bzip2
depends on libbzip2. bzip2 is only supported by lynx and some other console
text-browsers.

We currently limit to compression support to static files.

Caching
-------

mod_compress can store compressed files on disk to optimize the compression
on a second request away. As soon as compress.cache-dir is set the files are
compressed.

(You will need to create the cache directory if it doesn't already exist. The web server will not do this for you.  The directory will also need the proper ownership.  For Debian/Ubuntu the user and group ids should both be www-data.)

The names of the cache files are made of the filename, the compression method
and the etag associated to the file.

Cleaning the cache is left to the user. A cron job deleting files older than
10 days could do it: ::

  find /var/www/cache -type f -mtime +10 | xargs -r rm

Limitations
-----------

The module limits the compression of files to files smaller than 128 MByte and
larger than 128 Byte.

The lower limit is set as small files tend to become larger by compressing due
to the compression headers, the upper limit is set to work sensibly with
memory and cpu-time.

Directories containing a tilde ('~') are not created automatically (See ticket
#113). To enable compression for user dirs you have to create the directories
by hand in the cache directory.

Options
=======

compress.allowed-encodings
  override default set of allowed encodings

  e.g.: ::

    compress.allowed-encodings = ("bzip2", "gzip", "deflate")

compress.cache-dir
  name of the directory where compressed content will be cached

  e.g.: ::

    compress.cache-dir = "/var/www/cache/"

    # even better with virt-hosting
    $HTTP["host"] == "docs.example.org" {
      compress.cache-dir = "/var/www/cache/docs.example.org/"
    }

  Default: not set, compress the file for every request

compress.filetype
  mimetypes which might get compressed

  e.g.: ::

    compress.filetype           = ("text/plain", "text/html")

  Keep in mind that compressed JavaScript and CSS files are broken in some
  browsers. Not setting any filetypes will result in no files being compressed.

  NOTE: You have to specify the full mime-type! If you also define a charset, for example, you have to use "text/plain; charset=utf-8" instead of just "text/plain".

  Default: not set

compress.max-filesize
  maximum size of the original file to be compressed kBytes.

  This is meant to protect the server against DoSing as compressing large
  (let's say 1Gbyte) takes a lot of time and would delay the whole operation
  of the server.

  There is a hard upper limit of 128Mbyte.

  Default: unlimited (== hard-limit of 128MByte)

Display compressed files
========================

If you enable mod_compress, and you want to force clients to uncompress and display compressed text files, please force mimetype to nothing.
Exemple :
If you want to add headers for uncompress and display diff.gz files , add this section in your conf : ::

  $HTTP["url"] =~ "\.diff\.gz" {
    setenv.add-response-header = ( "Content-Encoding" => "gzip" )
    mimetype.assign = ()
  }


Compressing Dynamic Content
===========================

PHP
---

To compress dynamic content with PHP please enable ::

  zlib.output_compression = 1
  zlib.output_handler = On

in the php.ini as PHP provides compression support by itself.

mod_compress of lighttpd 1.5 r1992 may not set correct Content-Encoding with php-fcgi. A solution to that problem would be:

1.disable mod_compress when request a php file::

    $HTTP["url"] !~ "\.php$" {
    	compress.filetype = ("text/plain", "text/html", "text/javascript", "text/css", "text/xml")
    }

2.enable mod_setenv of your lighttpd::

    server.modules  += ( "mod_setenv" )

3.manually set Content-Encoding::

    $HTTP["url"] =~ "\.php$" {
  	setenv.add-response-header  = ( "Content-Encoding" => "gzip")
    }


TurboGears
----------

To compress dynamic content with TurboGears please enable ::

  [/]
  gzip_filter.on = True
  gzip_filter.mime_types = ["application/x-javascript", "text/javascript", "text/html", "text/css", "text/plain"]

in the config/app.cfg file in your TurboGears application.  The above lines should already be in the file.  You just need to remove the comment symbol in front of the lines to make them active.

Django
------

To compress dynamic content with Django please enable the GZipMiddleware ::

  MIDDLEWARE_CLASSES = (
      'django.middleware.gzip.GZipMiddleware',
      ...
  )

in the settings.py file in your Django project.

Catalyst
--------

To compress dynamic content with Perl/Catalyst, simply use the Catalyst::Plugin::Compress::Gzip module available on CPAN ::

  use Catalyst qw(
      Compress::Gzip
      ...
  );

in your main package (MyApp.pm). Further configuration is not required.

Using Authentication
====================

----------------
Module: mod_auth
----------------

:Author: Jan Kneschke
:Date: $Date$
:Revision: $Revision$

:abstract:
  The auth module provides ...

.. meta::
  :keywords: lighttpd, authentication

.. contents:: Table of Contents

Description
===========

Supported Methods
-----------------

lighttpd supportes both authentication method described by
RFC 2617:

basic
`````

The Basic method transfers the username and the password in
cleartext over the network (base64 encoded) and might result
in security problems if not used in conjunction with a crypted
channel between client and server.

digest
``````

The Digest method only transfers a hashed value over the
network which performs a lot of work to harden the
authentication process in insecure networks.

Backends
--------

Depending on the method lighttpd provides various way to store
the credentials used for the authentication.

for basic auth:

- plain_
- htpasswd_
- htdigest_
- ldap_

for digest auth:

- plain_
- htdigest_


plain
`````

A file which contains username and the cleartext password
seperated by a colon. Each entry is terminated by a single
newline.::

  e.g.:
  agent007:secret


htpasswd
````````

A file which contains username and the crypt()'ed password
seperated by a colon. Each entry is terminated by a single
newline. ::

  e.g.:
  agent007:XWY5JwrAVBXsQ

You can use htpasswd from the apache distribution to manage
those files. ::

  $ htpasswd lighttpd.user.htpasswd agent007


htdigest
````````

A file which contains username, realm and the md5()'ed
password seperated by a colon. Each entry is terminated
by a single newline. ::

  e.g.:
  agent007:download area:8364d0044ef57b3defcfa141e8f77b65

You can use htdigest from the apache distribution to manage
those files. ::

  $ htdigest lighttpd.user.htdigest 'download area' agent007

Using md5sum can also generate the password-hash: ::

  #!/bin/sh
  user=$1
  realm=$2
  pass=$3

  hash=`echo -n "$user:$realm:$pass" | md5sum | cut -b -32`

  echo "$user:$realm:$hash"

To use it:

  $ htdigest.sh 'agent007' 'download area' 'secret'
  agent007:download area:8364d0044ef57b3defcfa141e8f77b65



ldap
````

the ldap backend is basically performing the following steps
to authenticate a user

1. connect anonymously  (at plugin init)
2. get DN for filter = username
3. auth against ldap server
4. disconnect

if all 4 steps are performed without any error the user is
authenticated

Configuration
=============

::

  ## debugging
  # 0 for off, 1 for 'auth-ok' messages, 2 for verbose debugging
  auth.debug                 = 0

  ## type of backend
  # plain, htpasswd, ldap or htdigest
  auth.backend               = "htpasswd"

  # filename of the password storage for
  # plain
  auth.backend.plain.userfile = "lighttpd-plain.user"

  ## for htpasswd
  auth.backend.htpasswd.userfile = "lighttpd-htpasswd.user"

  ## for htdigest
  auth.backend.htdigest.userfile = "lighttpd-htdigest.user"

  ## for ldap
  # the $ in auth.backend.ldap.filter is replaced by the
  # 'username' from the login dialog
  auth.backend.ldap.hostname = "localhost"
  auth.backend.ldap.base-dn  = "dc=my-domain,dc=com"
  auth.backend.ldap.filter   = "(uid=$)"
  # if enabled, startTLS needs a valid (base64-encoded) CA
  # certificate
  auth.backend.ldap.starttls   = "enable"
  auth.backend.ldap.ca-file   = "/etc/CAcertificate.pem"

  ## restrictions
  # set restrictions:
  #
  # (  =>
  #   ( "method" => "digest"/"basic",
  #     "realm" => ,
  #     "require" => "user=" )
  # )
  #
  #  is a string to display in the dialog
  #         presented to the user and is also used for the
  #         digest-algorithm and has to match the realm in the
  #         htdigest file (if used)
  #

  auth.require = ( "/download/" =>
                   (
		     "method"  => "digest",
		     "realm"   => "download archiv",
		     "require" => "user=agent007|user=agent008"
		   ),
		   "/server-info" =>
                   (
		     "method"  => "digest",
		     "realm"   => "download archiv",
		     "require" => "valid-user"
		   )
                 )

Limitations
============

- The implementation of digest method is currently not
  completely compliant with the standard as it still allows
  a replay attack.

  The userdir module ...

.. meta::
  :keywords: lighttpd, userdir

.. contents:: Table of Contents

Description
===========

The userdir module provides a simple way to link user-based directories into the global namespace of the webserver.

Requests in the form ``/~user/page.html`` are rewritten to take the file ``page.html`` from the home directory of the user.
If ``userdir.path`` is set, the path will be appended to the home directory
building the classic mapping of: ::

  userdir.path = "public_html"

  URL: http://www.example.org/~jan/index.html
  Path: /home/jan/public_html/

To control which users should be able to use this feature you can set a list of usernames to include or exclude.

In case your mapping is independent of /etc/passwd you can use
``userdir.basepath``: ::

  userdir.path = "htdocs"
  userdir.basepath = "/var/www/users/"

  URL: http://www.example.org/~jan/index.html
  Path: /var/www/users/jan/htdocs/index.html

Options
=======

userdir.path (required option)
  usually it should be set to "public_html" to take ~/public_html/ as the document root

  Default: unset (mod_userdir disabled; set it to "" if you want the home directory to be the document root as it was the default before 1.4.19)
  Example: ::

    userdir.path = "public_html"

userdir.exclude-user
  list of usernames which may not use this feature

  Default: empty (all users may use it)
  Example: ::

    userdir.exclude-user = ( "root", "postmaster" )


userdir.include-user
  if set, only users from this list may use the feature

  Default: empty (all users may use it)

userdir.basepath
  if set, don't check /etc/passwd for homedir

  mod_dirlisting generates HTML based directory listings with full CSS

.. meta::
  :keywords: lighttpd, directory listings, dirlisting

.. contents:: Table of Contents

Description
===========

mod_dirlisting is one of the modules which is loaded by default and don't have to
be specified on server.modules to work.

A directory listing is generated if a directory is requested and no index-file
was found in that directory.

To enable directory listings globally: ::

  dir-listing.activate = "enable"

If you need it only for a directory, use conditionals: ::

  $HTTP["url"] =~ "^/download($|/)" {
    dir-listing.activate = "enable"
  }

You can also use a external generator for directory listings if you use
mod_indexfile. ::

  index-file.names = ( "/dir-generator.php" )

If a directory is requested the dir-generator.php is called instead which can
take the REQUEST_URI to see which directory was requested.

For large folders this is highly recommend.

Options
=======

dir-listing.activate
  enables virtual directory listings if a directory is requested no
  index-file was found

  Default: disabled

dir-listing.hide-dotfiles
  if enabled, does not list hidden files in directory listings generated
  by the dir-listing option.

  Default: enabled

dir-listing.external-css
  path to an external css stylesheet for the directory listing

dir-listing.exclude
  list of regular expressions.  Files that match any of the specified regular
  expressions will be excluded from directory listings.

dir-listing.encoding
  set a encoding for the generated directory listing

  If you file-system is not using ASCII you have to set the encoding of
  the filenames as they are put into the HTML listing AS IS (with XML
  encoding)

  Example: ::

    dir-listing.encoding = "utf-8"

dir-listing.show-readme
  shows README.txt after the dirlisting if it exists in the directory

  Default: disabled

dir-listing.hide-readme-file
  hides README.txt in the dirlisting

  Default: disabled

dir-listing.show-header
  shows HEADER.txt before the dirlisting if it exists in the directory

  Default: disabled

dir-listing.hide-header-file
  hides HEADER.txt in the dirlisting

  Default: disabled

dir-listing.set-footer

  Default: empty, uses server.tag instead

dir-listing.encode-readme
  encodes all control characers, '&', '<', '>' and '\x7f' as &#x**;

  Default: enabled

dir-listing.encode-header
  encodes all control characers, '&', '<', '>' and '\x7f' as &#x**;

  Default: enabled

dir-listing.auto-layout
  Disable this if you want your own html header and footer; specify
  them in HEADER.txt and README.txt

  you have to enable dir-list.show-readme/header for this of course

  .external-css and .set-footer will be ignored if this is disabled

  Default: enabled

  The proxy module a simplest way to connect lighttpd to
  java servers which have a HTTP-interface.

.. meta::
  :keywords: lighttpd, Proxy

.. contents:: Table of Contents

Description
===========

...

Options
=======

lighttpd provides the Proxy support via the proxy-module
(mod_proxy) which provides 2 options in the config-file:

:proxy.debug:
  a value between 0 and 65535 to set the debug-level in the
  Proxy module. Currently only 0 and 1 are used. Use 1 to
  enable some debug output, 0 to disable it.

:proxy.balance:
  might be one of 'hash', 'round-robin' or 'fair' (default).

  'round-robin' choses another host for each request, 'hash'
  is generating a hash over the request-uri and makes sure
  that the same request URI is sent to always the same host.
  That can increase the performance of the backend servers
  a lot due to higher cache-locality. 'fair' is the normal
  load-based, passive balancing.

:proxy.server:
  tell the module where to send Proxy requests to. Every
  file-extension can have its own handler. Load-Balancing is
  done by specifying multiple handles for the same extension.

  structure of proxy.server section: ::

    (  =>
      (
        ( "host" =>  ,
          "port" =>  ),
        ( "host" =>  ,
          "port" =>  )
      ),
       => ...
    )

  :: is the file-extension or prefix (if started with "/")
                might empty to match all requests
  :"host":      is ip of the proxy server
  :"port":      is tcp-port on the "host" used by the proxy
                server (default: 80)

  e.g.: ::

    proxy.server = ( ".jsp" =>
  		       ( (
		           "host" => "10.0.0.242",
		           "port" => 81
		         ) )
		     )

Example:
========

Using lighttpd + mod_proxy in front of 8 Squids which handle the
caching of dynamic content for you. All requests for the host
www.example.org should be forwarded to the proxy. All proxies
listen on port 80 for requests. ::

  $HTTP["host"] == "www.example.org" {
    proxy.balance = "hash"
    proxy.server  = ( "" => ( ( "host" => "10.0.0.10" ),
                              ( "host" => "10.0.0.11" ),
                              ( "host" => "10.0.0.12" ),
                              ( "host" => "10.0.0.13" ),
                              ( "host" => "10.0.0.14" ),
                              ( "host" => "10.0.0.15" ),
                              ( "host" => "10.0.0.16" ),
                              ( "host" => "10.0.0.17" ) ) )
  }

If one of the hosts goes down the all requests for this one server are
moved equally to the other servers. If you want to know more about
the algorithm used here google for 'Microsoft CARP'.

  The FastCGI interface is the fastest and most secure way
  to interface external process-handlers like Perl, PHP and
  your self-written applications.

.. meta::
  :keywords: lighttpd, FastCGI

.. contents:: Table of Contents

Description
===========

lighttpd provides an interface to a external programs that
support the FastCGI interface. The FastCGI Interface is
defined by http://www.fastcgi.com/ and is a
platform-independent and server independent interface between
a web-application and a webserver.

This means that FastCGI programs that run with the Apache
Webserver will run seamlessly with lighttpd and vice versa.


FastCGI
-------

FastCGI is removes a lot of the limitations of CGI programs.
CGI programs have the problem that they have to be restarted
by the webserver for every request which leads to really bad
performance values.

FastCGI removes this limitation by keeping the process running
and handling the requests by this always running process. This
removes the time used for the fork() and the overall startup
and cleanup time which is necessary to create and destroy a
process.

While CGI programs communicate to the server over pipes,
FastCGI processes use Unix-Domain-Sockets or TCP/IP to talk
with the webserver. This gives you the second advantage over
simple CGI programs: FastCGI don't have to run on the Webserver
itself but everywhere in the network.

lighttpd takes it a little bit further by providing a internal
FastCGI load-balancer which can be used to balance the load
over multiple FastCGI Servers. In contrast to other solutions
only the FastCGI process has to be on the cluster and not the
whole webserver. That gives the FastCGI process more resources
than a e.g. load-balancer+apache+mod_php solution.

If you compare FastCGI against a apache+mod_php solution you
should note that FastCGI provides additional security as the
FastCGI process can be run under different permissions that
the webserver and can also live a chroot which might be
different than the one the webserver is running in.

Options
=======

lighttpd provides the FastCGI support via the fastcgi-module
(mod_fastcgi) which provides 2 options in the config-file:

fastcgi.debug
  a value between 0 and 65535 to set the debug-level in the
  FastCGI module. Currently only 0 and 1 are used. Use 1 to
  enable some debug output, 0 to disable it.

fastcgi.map-extensions
  map multiple extensions to the same fastcgi server

  Example: ::

    fastcgi.map-extensions = ( ".php3" => ".php" )

fastcgi.server
  tell the module where to send FastCGI requests to. Every
  file-extension can have it own handler. Load-Balancing is
  done by specifying multiple handles for the same extension.

  structure of fastcgi.server section: ::

    (  =>
      (
        ( "host" =>  ,
          "port" =>  ,
          "socket" => ,       # either socket
                                      # or host+port
          "bin-path" => ,     # OPTIONAL
          "bin-environment" => , # OPTIONAL
          "bin-copy-environment" => , # OPTIONAL
          "mode" => ,         # OPTIONAL
          "docroot" =>  ,     # OPTIONAL if "mode"
                                      # is not "authorizer"
          "check-local" => ,  # OPTIONAL

                started if no local FastCGI is running
  :"socket":    path to the unix-domain socket

                Default is "responder", also "authorizer"
                mode is implemented.
  :"docroot":   is optional and is the docroot on the remote
                host for default "responder" mode. For
                "authorizer" mode it is MANDATORY and it points
                to docroot for authorized requests. For security
                reasons it is recommended to keep this docroot
                outside of server.document-root tree.
  :"check-local": is optional and may be "enable" (default) or
                "disable". If enabled the server first check
                for a file in local server.document-root tree
                and return 404 (Not Found) if no such file.
                If disabled, the server forward request to
                FastCGI interface without this check.
  :"broken-scriptfilename": breaks SCRIPT_FILENAME in a wat that
                PHP can extract PATH_INFO from it (default: disabled)
  :"disable-time": time to wait before a disabled backend is checked
                again

  :"bin-environment": put an entry into the environment of
                the started process
  :"bin-copy-environement": clean up the environment and copy
                only the specified entries into the fresh
                environment of the spawn process
  :"kill-signal": signal to terminate the FastCGI process with,
                defauls to SIGTERM

      ))
    )

  Example with prefix: ::

    fastcgi.server = ( "/remote_scripts/" =>
      (( "host" => "192.168.0.3",
         "port" => 9000,
         "check-local" => "disable",
         "docroot" => "/" # remote server may use
                          # it's own docroot
      ))
    )

  The request `http://my.host.com/remote_scripts/test.cgi` will
  be forwarded to fastcgi server at 192.168.0.3 and the value
  "/remote_scripts/test.cgi" will be used for the SCRIPT_NAME
  variable. Remote server may prepend it with its own
  document root. The handling of index files is also the
  resposibility of remote server for this case.

  In the case that the prefix is not terminated with a slash
  the prefix will be handled as file and /test.cgi would become
  a PATH_INFO instead of part of SCRIPT_NAME.


  Example for "authorizer" mode: ::

    fastcgi.server = ( "/remote_scripts/" =>
      (( "host" => "10.0.0.2",
         "port" => 9000,
         "docroot" => "/path_to_private_docs",
         "mode" => "authorizer"
      ))
    )

  Note that if "docroot" is specified then its value will be
  used in DOCUMENT_ROOT and SCRIPT_FILENAME variables passed
  to FastCGI server.

Load-Balancing
==============

The FastCGI plugin provides automaticly a load-balancing between
multiple FastCGI servers. ::

  fastcgi.server = ( ".php" =>
     (( "host" => "10.0.0.2", "port" => 1030 ),
      ( "host" => "10.0.0.3", "port" => 1030 ))
    )


To understand how the load-balancing works you can enable the
fastcgi.debug option and will get a similar output as here: ::

  proc: 127.0.0.1 1031  1 1 1 31454
  proc: 127.0.0.1 1028  1 1 1 31442
  proc: 127.0.0.1 1030  1 1 1 31449
  proc: 127.0.0.1 1029  1 1 2 31447
  proc: 127.0.0.1 1026  1 1 2 31438
  got proc: 34 31454
  release proc: 40 31438
  proc: 127.0.0.1 1026  1 1 1 31438
  proc: 127.0.0.1 1028  1 1 1 31442
  proc: 127.0.0.1 1030  1 1 1 31449
  proc: 127.0.0.1 1031  1 1 2 31454
  proc: 127.0.0.1 1029  1 1 2 31447

Even if this for multiple FastCGI children on the local machine
the following explaination is valid for remote connections too.

The output shows:

- IP, port, unix-socket (is empty here)
- is-local, state (0 - unset, 1 - running, ... )
- active connections (load)
- PID

As you can see the list is always sorted by the load field.

Whenever a new connection is requested, the first entry (the one
with the lowest load) is selected, the load is increased (got proc: ...)
and the list is sorted again.

If a FastCGI request is done or the connection is dropped, the load on the
FastCGI proc decreases and the list is sorted again (release proc: ...)

This behaviour is very light-weight in code and still very efficient
as it keeps the fastcgi-servers equally loaded even if they have different
CPUs.

Adaptive Process Spawning
=========================

.. note:: This feature is disabled in 1.3.14 again. min-procs is
          ignored in that release

Starting with 1.3.8 lighttpd can spawn processes on demand if
a bin-path is specified and the FastCGI process runs locally.

If you want to have a least one FastCGI process running and
more of the number of requests increases you can use min-procs
and max-procs.

A new process is spawned as soon as the average number of
requests waiting to be handle by a single process increases the
max-load-per-proc setting.

The idle-timeout specifies how long a fastcgi-process should wait
for a new request before it kills itself.

Example
-------
::

  fastcgi.server = ( ".php" =>
    (( "socket" => "/tmp/php.socket",
       "bin-path" => "/usr/local/bin/php",
       "min-procs" => 1,
       "max-procs" => 32,
       "max-load-per-proc" => 4,
       "idle-timeout" => 20
    ))
   )

Disabling Adaptive Spawning
---------------------------

Adaptive Spawning is a quite new feature and it might misbehave
for your setup. There are several ways to control how the spawing
is done:

1. ``"max-load-per-proc" => 1``
   if that works for you, great.

2. If not set ``min-procs == max-procs``.

3. For PHP you can also use: ::

     $ PHP_FCGI_CHILDREN=384 ./lighttpd -f ./lighttpd.conf

     fastcgi.server = ( ".php" =>
        (( "socket" => "/tmp/php.socket",
           "bin-path" => "/usr/local/bin/php",
           "min-procs" => 1,
           "max-procs" => 1,
           "max-load-per-proc" => 4,
           "idle-timeout" => 20
        ))
      )

   It will create one socket and let's PHP create the 384 processes itself.

4. If you don't want lighttpd to manage the fastcgi processes, remove the
   bin-path and use spawn-fcgi to spawn them itself.


FastCGI and Programming Languages
=================================

Preparing PHP as a FastCGI program
----------------------------------

One of the most important application that has a FastCGI
interface is php which can be downloaded from
http://www.php.net/ . You have to recompile the php from
source to enable the FastCGI interface as it is normally
not enabled by default in the distributions.

If you already have a working installation of PHP on a
webserver execute a small script which just contains ::

  

and search for the line in that contains the configure call.
You can use it as the base for the compilation.

You have to remove all occurences of `--with-apxs`, `--with-apxs2`
and the like which would build PHP with Apache support.  Add the
next three switches to compile PHP with FastCGI support::

  $ ./configure \
    --enable-fastcgi \
    --enable-force-cgi-redirect \
    ...

After compilation and installation check that your PHP
binary contains FastCGI support by calling: ::

  $ php -v
  PHP 4.3.3RC2-dev (cgi-fcgi) (built: Oct 19 2003 23:19:17)

The important part is the (cgi-fcgi).


Starting a FastCGI-PHP
----------------------

Starting with version 1.3.6 lighttpd can spawn the FastCGI
processes locally itself if necessary: ::

  fastcgi.server = ( ".php" =>
    (( "socket" => "/tmp/php-fastcgi.socket",
       "bin-path" => "/usr/local/bin/php"
    ))
  )

PHP provides 2 special environment variables which control the number of
spawned workes under the control of a single watching process
(PHP_FCGI_CHILDREN) and the number of requests what a single worker
handles before it kills itself. ::

  fastcgi.server = ( ".php" =>
     (( "socket" => "/tmp/php-fastcgi.socket",
        "bin-path" => "/usr/local/bin/php",
        "bin-environment" => (
          "PHP_FCGI_CHILDREN" => "16",
          "PHP_FCGI_MAX_REQUESTS" => "10000"
        )
     ))
   )

To increase the security of the started process you should only pass
the necessary environment variables to the FastCGI process. ::

  fastcgi.server = ( ".php" =>
     (( "socket" => "/tmp/php-fastcgi.socket",
        "bin-path" => "/usr/local/bin/php",
        "bin-environment" => (
           "PHP_FCGI_CHILDREN" => "16",
           "PHP_FCGI_MAX_REQUESTS" => "10000" ),
        "bin-copy-environment" => (
           "PATH", "SHELL", "USER" )
     ))
   )

Configuring PHP
---------------

If you want to use PATH_INFO and PHP_SELF in you PHP scripts you have to
configure php and lighttpd. The php.ini needs the option: ::

  cgi.fix_pathinfo = 1

and the option ``broken-scriptfilename`` in your fastcgi.server config: ::

  fastcgi.server = ( ".php" =>
     (( "socket" => "/tmp/php-fastcgi.socket",
        "bin-path" => "/usr/local/bin/php",
        "bin-environment" => (
          "PHP_FCGI_CHILDREN" => "16",
          "PHP_FCGI_MAX_REQUESTS" => "10000" ),
        "bin-copy-environment" => (
          "PATH", "SHELL", "USER" ),
        "broken-scriptfilename" => "enable"
     ))
   )

Why this ? the ``cgi.fix_pathinfo = 0`` would give you a working ``PATH_INFO``
but no ``PHP_SELF``. If you enable it, it turns around. To fix the
``PATH_INFO`` `--enable-discard-path` needs a SCRIPT_FILENAME which is against the CGI spec, a
broken-scriptfilename. With ``cgi.fix_pathinfo = 1`` in php.ini and
``broken-scriptfilename => "enable"`` you get both.


External Spawning
-----------------

Spawning FastCGI processes directly in the webserver has some
disadvantages like

- FastCGI process can only run locally
- has the same permissions as the webserver
- has the same base-dir as the webserver

As soon as you are using a seperate FastCGI Server to
take off some load from the webserver you have to control
the FastCGI process by a external program like spawn-fcgi.

spawn-fcgi is used to start a FastCGI process in its own
environment and set the user-id, group-id and change to
another root-directory (chroot).

For convenience a wrapper script should be used which takes
care of all the necessary option. Such a script in included
in the lighttpd distribution and is call spawn-php.sh.

The script has a set of config variables you should take
a look at: ::

  ## ABSOLUTE path to the spawn-fcgi binary
  SPAWNFCGI="/usr/local/sbin/spawn-fcgi"

  ## ABSOLUTE path to the PHP binary
  FCGIPROGRAM="/usr/local/bin/php"

  ## bind to tcp-port on localhost
  FCGIPORT="1026"

  ## bind to unix domain socket
  # FCGISOCKET="/tmp/php.sock"

  ## number of PHP childs to spawn
  PHP_FCGI_CHILDREN=10

  ## number of request server by a single php-process until
  ## is will be restarted
  PHP_FCGI_MAX_REQUESTS=1000

  ## IP adresses where PHP should access server connections
  ## from
  FCGI_WEB_SERVER_ADDRS="127.0.0.1,192.168.0.1"

  # allowed environment variables sperated by spaces
  ALLOWED_ENV="ORACLE_HOME PATH USER"

  ## if this script is run as root switch to the following user
  USERID=wwwrun
  GROUPID=wwwrun

If you have set the variables to values that fit to your
setup you can start it by calling: ::

  $ spawn-php.sh
  spawn-fcgi.c.136: child spawned successfully: PID: 6925

If you get "child spawned successfully: PID:" the php
processes could be started successfully. You should see them
in your processlist: ::

  $ ps ax | grep php
  6925 ?        S      0:00 /usr/local/bin/php
  6928 ?        S      0:00 /usr/local/bin/php
  ...

The number of processes should be PHP_FCGI_CHILDREN + 1.
Here the process 6925 is the master of the slaves which
handle the work in parallel. Number of parallel workers can
be set by PHP_FCGI_CHILDREN. A worker dies automaticly of
handling PHP_FCGI_MAX_REQUESTS requests as PHP might have
memory leaks.

If you start the script as user root php processes will be
running as the user USERID and group GROUPID to drop the
root permissions. Otherwise the php processes will run as
the user you started script as.

As the script might be started from a unknown stage or even
directly from the command-line it cleans the environment
before starting the processes. ALLOWED_ENV contains all
the external environement variables that should be available
to the php-process.


Perl
----

For Perl you have to install the FCGI module from CPAN.

Skeleton for remote authorizer
==============================

The basic functionality of authorizer is as follows (see
http://www.fastcgi.com/devkit/doc/fcgi-spec.html, 6.3 for
details). ::

  #include 
  #include 
  #include 
  int main () {
    char* p;

    while (FCGI_Accept() >= 0) {
      /* wait for fastcgi authorizer request */

      printf("Content-type: text/html\r\n");

      if ((p = getenv("QUERY_STRING")) == NULL) ||
           )
           printf("Status: 403 Forbidden\r\n\r\n");

      else printf("\r\n");
        /* default Status is 200 - allow access */
    }

    return 0;
  }

It is possible to use any other variables provided by
FastCGI interface for authorization check. Here is only an
example.


Troubleshooting
===============

fastcgi.debug should be enabled for troubleshooting.

If you get: ::

  (fcgi.c.274) connect delayed:  8
  (fcgi.c.289) connect succeeded:  8
  (fcgi.c.745) unexpected end-of-file (perhaps the fastcgi
     process died):  8

the fastcgi process accepted the connection but closed it
right away. This happens if FCGI_WEB_SERVER_ADDRS doesn't
include the host where you are connection from.

If you get ::

  (fcgi.c.274) connect delayed:  7
  (fcgi.c.1107) error: unexpected close of fastcgi connection
     for /peterp/seite1.php (no fastcgi process on host/port ?)
  (fcgi.c.1015) emergency exit: fastcgi: connection-fd: 5
     fcgi-fd: 7

the fastcgi process is not running on the host/port you are
connection to. Check your configuration.

If you get ::

  (fcgi.c.274) connect delayed:  7
  (fcgi.c.289) connect succeeded:  7

everything is fine. The connect() call just was delayed a
little bit and is completly normal.

  The plugin interface is an integral part of lighttpd which
  provides a flexible way to add specific functionality to lighttpd.

.. meta::
  :keywords: lighttpd, plugins

.. contents:: Table of Contents

Description
===========

Plugins allow you to enhance the functionality of lighttpd without
changing the core of the webserver. They can be loaded at startup time
and can change virtually any aspect of the behaviour of the webserver.

Plugin Entry Points
-------------------

lighttpd has 16 hooks which are used in different states of the
execution of the request:

Serverwide hooks
````````````````

:init_:
  called when the plugin is loaded
:cleanup_:
  called when the plugin is unloaded
:set_defaults_:
  called when the configuration has to be processed
:handle_trigger_:
  called once a second
:handle_sighup_:
  called when the server received a SIGHUP

Connectionwide hooks
````````````````````

Most of these hooks are called in ``http_response_prepare()`` after some
fields in the connection structure are set.

:handle_uri_raw_:
  called after uri.path_raw, uri.authority and uri.scheme are set
:handle_uri_clean_:
  called after uri.path (a clean URI without .. and %20) is set
:handle_docroot_:
  called at the end of the logical path handle to get a docroot
:handle_subrequest_start_:
  called if the physical path is set up and checked
:handle_subrequest_:
  called at the end of ``http_response_prepare()``
:handle_physical_path_:
  called after the physical path is created and no other handler is
  found for this request
:handle_request_done_:
  called when the request is done
:handle_connection_close_:
  called if the connection has to be closed
:handle_joblist_:
  called after the connection_state_engine is left again and plugin
  internal handles have to be called
:connection_reset_:
  called if the connection structure has to be cleaned up


Plugin Interface
----------------

\*_plugin_init
``````````````

Every plugin has a uniquely-named function which is called after the
plugin is loaded. It is used to set up the ``plugin`` structure with
some useful data:

- name of the plugin ``name``
- all hooks

The field ``data`` and ``lib`` should not be touched in the init function.
``lib`` is the library handler from dlopen and ``data`` will be the storage
of the internal plugin data.

:returns:
  0 (not handled)

init
````

The first real call of a plugin function is the init hook which is used
to set up the internal plugin data. The internal plugin is assigned the
``data`` field mentioned in the \*_plugin_init description.

:returns:
  a pointer to the internal plugin data.

cleanup
```````

The cleanup hook is called just before the plugin is unloaded. It is meant
to free all buffers allocated in ``init`` or somewhere else in the plugin
which are still not freed and to close all handles which were opened and
are not closed yet.

:returns:
  HANDLER_GO_ON if ok (not handled)

set_defaults
````````````

set_defaults is your entry point into the configfile parsing. It should
pass a list of options to ``config_insert_values`` and check if
the plugin configuration is valid. If it is not valid yet, it should
set useful defaults or return with HANDLER_ERROR and an error message.

:returns:
  HANDLER_GO_ON if ok

  HANDLER_ERROR will terminate lighttpd

connection_reset
````````````````

called at the end of each request

:returns:
  HANDLER_GO_ON if ok

  HANDLER_ERROR on error

handle_trigger
``````````````

called once a second

:returns:
  HANDLER_GO_ON if ok

  HANDLER_ERROR on error

handle_sighup
`````````````

called if a SIGHUP is received (cycling logfiles, ...)

:returns:
  HANDLER_GO_ON if ok

  HANDLER_ERROR on error

handle_uri_raw
``````````````

called after uri_raw is set

:returns:
  HANDLER_GO_ON if ok
  HANDLER_FINISHED if the final output is prepared

  HANDLER_ERROR on error

handle_uri_clean
````````````````

called after uri.path is set

:returns:
  HANDLER_GO_ON if ok
  HANDLER_FINISHED if the final output is prepared

  HANDLER_ERROR on error

handle_docroot
``````````````

called when a docroot is needed

:returns:
  HANDLER_GO_ON if ok
  HANDLER_FINISHED if the final output is prepared

  HANDLER_ERROR on error

handle_subrequest_start
```````````````````````

called after physical.path is set

:returns:
  HANDLER_GO_ON if ok
  HANDLER_FINISHED if the final output is prepared

  HANDLER_ERROR on error

handle_subrequest
`````````````````

called if subrequest_start requested a COMEBACK or a WAIT_FOR_EVENT

:returns:
  HANDLER_GO_ON if ok
  HANDLER_FINISHED if the final output is prepared

  HANDLER_ERROR on error

handle_physical_path
````````````````````

called after physical.path is set

:returns:
  HANDLER_GO_ON if ok
  HANDLER_FINISHED if the final output is prepared

  HANDLER_ERROR on error


handle_request_done
```````````````````

called at the end of the request (logging, statistics, ...)

:returns:
  HANDLER_GO_ON if ok

  HANDLER_ERROR on error

handle_connection_close
```````````````````````

called if the connection is terminated

:returns:
  HANDLER_GO_ON if ok

  HANDLER_ERROR on error

handle_joblist
``````````````

called if the state of the connection has changed

:returns:
  HANDLER_GO_ON if ok

  HANDLER_ERROR on error

  WebDAV module for lighttpd

.. meta::
  :keywords: lighttpd, webdav

.. contents:: Table of Contents

Description
===========

The WebDAV module is a very minimalistic implementation of RFC 2518.
Minimalistic means that not all operations are implemented yet.

So far we have

 * PROPFIND
 * OPTIONS
 * MKCOL
 * DELETE
 * PUT

and the usual GET, POST, HEAD from HTTP/1.1.

So far, mounting a WebDAV resource into Windows XP works and the basic litmus
tests are passed.

Options
=======

webdav.activate
  If you load the webdav module, the WebDAV functionality has to be
  enabled for the directories you want to provide to the user.

  Default: disable

webdav.is-readonly
  Only allow reading methods (GET, PROPFIND, OPTIONS) on WebDAV resources.

  Default: writable

Examples
========

To enable WebDAV for the /dav directory, you wrap your webdav options in
a conditional. You have to use the regex like below as you want to match
the directory /dav and everything below it, but not e.g. /davos. ::

  $HTTP["url"] =~ "^/dav($|/)" {
    webdav.activate = "enable"
    webdav.is-readonly = "enable"
  }

  name of the file where the accesslog should be written too if syslog
  is not used.

  if the name starts with a '|' the rest of the name is taken
  as the name of a process which will be spawn and will get the
  output

  e.g.: ::

    accesslog.filename = "/var/log/lighttpd.log"

    $HTTP["host"] == "mail.example.org" {
      accesslog.filename = "|/usr/bin/cronolog"
    }

  Default: disabled

accesslog.format
  the format of the logfile

  ====== ================================
  Option Description
  ====== ================================
  %%     a percent sign
  %h     name or address of remote-host
  %l     ident name (not supported)

  %I     bytes incomming
  %O     bytes outgoing
  ====== ================================

  If %s is written %>s or % are ignored. They are support
  for compat with apache.

  %i and %o expect the name of the field which should be written in curly brackets.

  e.g.: ::

    accesslog.format = "%h %l %u %t \"%r\" %b %>s \"%{User-Agent}i\" \"%{Referer}i\""

  Default: CLF compatible output

Response Header
---------------

The accesslog module provides a special way to log content from the
application in a accesslog file. It can be used to log the session id into a
logfile.

If you want to log it into the accesslog just specify the field-name within
a %{...}o like ::

  accesslog.format = "%h %l %u %t \"%r\" %b %>s \"%{User-Agent}i\" \"%{Referer}i\" \"%{X-LIGHTTPD-SID}o\""

The prefix ``X-LIGHTTPD-`` is special as every response header starting with
this prefix is assumed to be special for lighttpd and won't be sent out
to the client.

An example the use this functionality is provided below: ::

.. meta::
  :keywords: lighttpd, bandwidth limit, traffic shaping

.. contents:: Table of Contents

Description
===========

Starting with 1.3.8, lighttpd supports limiting the bandwidth for
a single connection or config context like a virtual host or a URL.

Options
=======

:connection.kbytes-per-second:
  limit the throughput for each single connection to the given
  limit in kbyte/s

  default: 0 (no limit)

:server.kbytes-per-second:
  limit the throughput for all connections to the given limit
  in kbyte/s

  if you want to specify a limit for a special virtual server
  use: ::

    $HTTP["host"] == "www.example.org" {
      server.kbytes-per-second = 128
    }

  which will override the default for this host.

  default: 0 (no limit)

Additional Notes
================

Keep in mind that a limit below 32kb/s might actually limit the traffic to 32kb/s. This
is caused by the size of the TCP send buffer.

  authenticated file requests and a countermeasure against
  deep-linking can be achieved easily by using mod_secdownload

.. meta::
  :keywords: lighttpd, secure, fast, downloads

.. contents:: Table of Contents

Options
=======

::

  secdownload.secret        = 
  secdownload.document-root = 
  secdownload.uri-prefix    =   (default: /)
  secdownload.timeout       =    (default: 60 seconds)

Description
===========

there are multiple ways to handle secured download mechanisms:

1. use the webserver and the internal HTTP authentication
2. use the application to authenticate and send the file
   through the application

Both ways have limitations:

webserver:

- ``+`` fast download
- ``+`` no additional system load
- ``-`` inflexible authentication handling

application:

- ``+`` integrated into the overall layout
- ``+`` very flexible permission management
- ``-`` the download occupies an application thread/process

A simple way to combine the two ways could be:

1. app authenticates user and checks permissions to
   download the file.
2. app redirects user to the file accessable by the webserver
   for further downloading.
3. the webserver transfers the file to the user.

As the webserver doesn't know anything about the permissions
used in the app, the resulting URL would be available to every
user who knows the URL.

mod_secdownload removes this problem by introducing a way to
authenticate a URL for a specified time. The application has
to generate a token and a timestamp which are checked by the
webserver before it allows the file to be downloaded by the
webserver.

The generated URL has to have the format:

/

 is an MD5 of

1. a secret string (user supplied)
2.  (starts with /)
3. 


As you can see, the token is not bound to the user at all. The
only limiting factor is the timestamp which is used to
invalidate the URL after a given timeout (secdownload.timeout).

.. Note::
  Be sure to choose a another secret than the one used in the
  examples, as this is the only part of the token that is not
  known to the user.



If the user tries to fake the URL by choosing a random token,
status 403 'Forbidden' will be sent out.

If the timeout is reached, status 408 'Request Timeout' will be
sent. (This does not really conform to the standard, but should
do the trick).

If token and timeout are valid, the  is appended to
the configured (secdownload.document-root) and passed to the
normal internal file transfer functionality. This might lead to
status 200 or 404.

Example
=======

Application
-----------

Your application has to generate the correct URLs. The following sample
code for PHP should be easily adaptable to any other language: ::

  %s',
         $uri_prefix, $m, $t_hex, $f, $f);
  ?>

Webserver
---------

The server has to be configured in the same way. The URI prefix and
secret have to match: ::

  server.modules = ( ..., "mod_secdownload", ... )

  secdownload.secret          = "verysecret"
  secdownload.document-root   = "/home/www/servers/download-area/"
  secdownload.uri-prefix      = "/dl/"
  secdownload.timeout         = 120

Basic Syntax
------------

A BNF like notation: ::

  option   : NAME = VALUE
  merge    : NAME += VALUE
  NAME     : modulename.key
  VALUE    : (  |  |  |  | VALUE [ + VALUE ]*)
   : "text"
  : digit*
  : ( "enable" | "disable" )
    : "(" [  "=>" ]  [, [  "=>" ]  ]* ")"
  INCLUDE  : "include" VALUE
  INCLUDE_SHELL : "include_shell" STRING_VALUE

Example
-------

::

  # default document-root
  server.document-root = "/var/www/example.org/pages/"

  # TCP port
  server.port = 80

  # selecting modules
  server.modules = ( "mod_access", "mod_rewrite" )

  # variables, computed when config is read.
  var.mymodule = "foo"
  server.modules += ( "mod_" + var.mymodule )
  # var.PID is initialised to the pid of lighttpd before config is parsed

  # include, relative to dirname of main config file
  include "mime.types.conf"

  # read configuration from output of a command
  include_shell "/usr/local/bin/confmimetype /etc/mime.types"


Conditional Configuration
=========================

Most options can be configured conditionally by using the following syntax
(including nesting).

::

     {
    ...
       {
      ... nesting: match only when parent match
    }
  }
  else    {
    ... the "else if" block
  }

where  is one of one of the following:

$HTTP["cookie"]
  match on cookie
$HTTP["scheme"]
  match on scheme
$HTTP["host"]
  match on host
$HTTP["useragent"]
$HTTP["user-agent"]
  match on useragent
$HTTP["referer"]
  match on referer
$HTTP["method"]
  math on the http method
$HTTP["url"]
  match on url
$HTTP["query-string"]
  match on the (not decoded) query-string
$HTTP["remoteip"]
$HTTP["remote-ip"]
  match on the remote IP or a remote Network
$HTTP["language"]
  match on the Accept-Language header
$SERVER["socket"]
  match on socket. Value must be on the format "ip:port" where ip is an IP
  address and port a port number. Only equal match (==) is supported.
  It also binds the daemon to this socket. Use this if you want to do IP/port-
  based virtual hosts.

 is one of:

==
  string equal match
!=
  string not equal match
=~
  perl style regular expression match
!~
  perl style regular expression not match

and  is either a quoted ("") literal string or regular expression.


Example
-------

::

  # disable directory-listings for /download/*
  dir-listing.activate = "enable"
  $HTTP["url"] =~ "^/download/" {
    dir-listing.activate = "disable"
  }

  # handish virtual hosting
  # map all domains of a top-level-domain to a single document-root
  $HTTP["host"] =~ "(^|\.)example\.org$" {
    server.document-root = "/var/www/htdocs/example.org/pages/"
  }

  # multiple sockets
  $SERVER["socket"] == "127.0.0.1:81" {
    server.document-root = "..."
  }

  $SERVER["socket"] == "127.0.0.1:443" {
    ssl.pemfile = "/var/www/certs/localhost.pem"
    ssl.engine = "enable"

    server.document-root = "/var/www/htdocs/secure.example.org/pages/"
  }

  # deny access for all googlebot
  $HTTP["useragent"] =~ "Google" {
    url.access-deny = ( "" )
  }

  # deny access for all image stealers
  $HTTP["referer"] !~ "^($|http://www\.example\.org)" {
    url.access-deny = ( ".jpg", ".jpeg", ".png" )
  }

  # deny the access to www.example.org to all user which
  # are not in the 10.0.0.0/8 network
  $HTTP["host"] == "www.example.org" {
    $HTTP["remoteip"] != "10.0.0.0/8" {
     url.access-deny = ( "" )
    }
  }

Using variables
===============

You can set your own variables in the configuration to simplify your config.
::

  var.basedir = "/home/www/servers/"
  $HTTP["host"] == "www.example.org" {
     server.name = "www.example.org"
     include "incl-base.conf"
  }

  in incl-base.conf:
  server.document-root = basedir + server.name + "/pages/"
  accesslog.filename   = basedir + server.name + "/logs/access.log"

You can also use environement variables or the default variables var.PID and
var.CWD: ::

  var.basedir = env.LIGHTTPDBASE

  $HTTP["host"] == "www.example.org" {
     server.name = "www.example.org"
     include "incl-base.conf"
     include "incl-fastcgi.conf"
  }

  in incl-fastcgi.conf:
  fastcgi.server = ( ... => ((
     "socket" => basedir + server.name + "/tmp/fastcgi-" + PID + ".sock"
  )) )

Or like the lighttpd script for rails does:

  var.basedir = var.CWD

  server.document-root = basedir + "/public/"

Global context
==============

::

  global {
    ...
  }

You don't need it in the main configuration file. But you might have
difficulty setting server wide configuration inside a included-file from
conditionals.

Example
-------

::

  in lighttpd.conf:
  server.modules = ()
  $HTTP["host"] == "www.example.org" {
    include "incl-php.conf"
  }

  in incl-php.conf:
  global {
    server.modules += ("mod_fastcgi")
    static-file.exclude-extensions += (".php")
  }
  fastcgi.server = "..."

server.tag
  set the string returned by the Server: response header

  Default: lighttpd 

server.errorlog
  pathname of the error-log

  Default: either STDERR or ``server.errorlog-use-syslog``

  root-directory of the server

  NOTE: requires root-permissions

server.username
  username used to run the server

  NOTE: requires root-permissions

server.groupname
  groupname used to run the server

  NOTE: requires root-permissions

server.follow-symlink

  Default: enabled

index-file.names
  list of files to search for if a directory is requested
  e.g.: ::

    index-file.names          = ( "index.php", "index.html",
                                  "index.htm", "default.htm" )

  if a name starts with slash this file will be used a index generator
  for all directories.

server.modules
  modules to load

.. note:: the order of the modules is important.

  The modules are executed in the order as they are specified. Loading
  mod_auth AFTER mod_fastcgi might disable authentication for fastcgi
  backends (if check-local is disabled).

  As auth should be done first, move it before all executing modules (like
  proxy, fastcgi, scgi and cgi).

  rewrites, redirects and access should be first, followed by auth and
  the docroot plugins.

  Afterwards the external handlers like fastcgi, cgi, scgi and proxy and
  at the bottom the post-processing plugins like mod_accesslog.

  e.g.: ::

    server.modules          = ( "mod_rewrite",
                                "mod_redirect",
				"mod_alias",
			        "mod_access",
				"mod_auth",
                                "mod_status",
				"mod_simple_vhost",
				"mod_evhost",
				"mod_userdir",
				"mod_secdownload",
				"mod_fastcgi",
				"mod_proxy",
				"mod_cgi",
                                "mod_ssi",
				"mod_compress",
                                "mod_usertrack",
				"mod_expire",
 				"mod_rrdtool",
				"mod_accesslog" )

  Starting with lighttpd 1.4.0 three default modules are loaded automaticly:

  - mod_indexfile
  - mod_dirlisting
  - mod_staticfile

server.event-handler
  set the event handler

  Default: "poll"

server.pid-file
  set the name of the .pid-file where the PID of the server should be placed.
  This option is used in combination with a start-script and the daemon mode

  Default: not set

server.max-request-size
  maximum size in kbytes of the request (header + body). Only applies to POST
  requests.

  Default: 2097152 (2GB)

server.max-worker
  number of worker processes to spawn. This is usually only needed on servers
  which are fairly loaded and the network handler calls delay often (e.g. new
  requests are not handled instantaneously).

  Default: 0

server.name
  name of the server/virtual server

  Default: hostname

server.max-keep-alive-requests
  maximum number of request within a keep-alive session before the server
  terminates the connection

  Default: 128

server.max-keep-alive-idle
  maximum number of seconds until a idling keep-alive connection is droped

  Default: 30

server.max-read-idle
  maximum number of seconds until a waiting, non keep-alive read times out
  and closes the connection

  Default: 60

server.max-write-idle
  maximum number of seconds until a waiting write call times out and closes
  the connection

  Default: 360

server.error-handler-404
  uri to call if the requested file results in a 404

  Default: not set

  Example: ::

    server.error-handler-404 = "/error-404.php"

server.protocol-http11
  defines if HTTP/1.1 is allowed or not.

  Default: enabled

server.range-requests
  defines if range requests are allowed or not.

  Default: enabled


SSL engine
``````````

ssl.pemfile
  path to the PEM file for SSL support

debug.dump-unknown-headers
  enables listing of internally unhandled HTTP-headers

  e.g. ::

    debug.dump-unknown-headers = "enable"

mimetypes
`````````

mimetype.assign
  list of known mimetype mappings
  NOTE: if no mapping is given "application/octet-stream" is used

			  ".html" => "text/html",
  			  ".txt"  => "text/plain" )

  The list is compared top down and the first match is taken. This is
  important if you have matches like: ::

                          ".tar.gz" => "application/x-tgz",
			  ".gz" => "application/x-gzip",

  If you want to set another default mimetype use: ::

                          ...,
                          "" => "text/plain" )

  as the last entry in the list.

mimetype.use-xattr
  If available, use the XFS-style extended attribute interface to
  retrieve the "Content-Type" attribute on each file, and use that as the
  mime type. If it's not defined or not available, fall back to the
  mimetype.assign assignment.

  e.g.: ::

    mimetype.use-xattr = "enable"

    on shell use:

    $ attr -s Content-Type -V image/svg svgfile.svg

    or

    $ attr -s Content-Type -V text/html indexfile

Description
===========

CGI programs allow you to enhance the functionality of the server in a very
straight and simple way..

Options
=======

cgi.assign

  file-extensions that are handled by a CGI program

  e.g.: ::

    cgi.assign = ( ".pl"  => "/usr/bin/perl",
                   ".cgi" => "/usr/bin/perl" )

Examples
========

To setup a executable which doesn't need the help of a external program you
just don't specify a handler for the extension. ::

  cgi.assign = ( ".sh" => "" )

If the file has no extension keep in mind that lighttpd matches not the
extension itself but the right part of the URL: ::

  cgi.assign = ( "/testfile" => "" )

  How to set up SSL in lighttpd

.. meta::
  :keywords: lighttpd, ssl

.. contents:: Table of Contents

Description
===========

lighttpd supports SSLv2 and SSLv3 if it is compiled against openssl.

Configuration
-------------

To enable SSL for the whole server you have to provide a valid
certificate and have to enable the SSL engine.::

  ssl.engine = "enable"
  ssl.pemfile = "/path/to/server.pem"

The HTTPS protocol does not allow you to use name-based virtual
hosting with SSL. If you want to run multiple SSL servers with
one lighttpd instance you must use IP-based virtual hosting: ::

  $SERVER["socket"] == "10.0.0.1:443" {
    ssl.engine                  = "enable"
    ssl.pemfile                 = "www.example.org.pem"
    server.name                 = "www.example.org"

    server.document-root        = "/www/servers/www.example.org/pages/"
  }

If you have a .crt and a .key file, cat them together into a
single PEM file:
::

  $ cat host.key host.crt > host.pem


Self-Signed Certificates
------------------------

A self-signed SSL certificate can be generated like this: ::

  $ openssl req -new -x509 \
    -keyout server.pem -out server.pem \
    -days 365 -nodes

Description
===========

With MySQL-based vhosting you can store the path to a given host's
document root in a MySQL database.

.. note:: Keep in mind that only one vhost module should be active at a time.
          Don't mix mod_simple_vhost with mod_mysql_vhost.

  mysql-vhost.sql            = "SELECT docroot FROM domains WHERE domain='?'"


MySQL setup: ::

  GRANT SELECT ON lighttpd.* TO lighttpd@localhost IDENTIFIED BY 'secret';

  CREATE DATABASE lighttpd;

  USE lighttpd;

  CREATE TABLE domains (
    domain varchar(64) not null primary key,

Description
===========

Anti Hotlinking:

 * if user requests ''download-url'' directly, the request is denied and he is redirected to ''deny-url'
 * if user visits ''trigger-url'' before requesting ''download-url'', access is granted
 * if user visits ''download-url'' again after ''trigger-timeout'' has elapsed, the request is denied and he is redirected to ''deny-url''

The trigger information is either stored locally in a gdbm file or remotely in memcached.

Requirements
------------

 * libpcre
 * libgdbm or libmemcache

Options
=======

::

  trigger-before-download.gdbm-filename = "/home/weigon/testbase/trigger.db"
  trigger-before-download.memcache-hosts = ( "127.0.0.1:11211" )
  trigger-before-download.trigger-url = "^/trigger/"

  trigger-before-download.deny-url = "http://192.168.1.5:1025/index.html"
  trigger-before-download.trigger-timeout = 10

If both trigger-before-download.gdbm-filename and
trigger-before-download.memcache-hosts is set gdbm will take precedence.

Installation
============

memcached should be started with the option -M as we don't want to remove entry if the memory is full.

mod_extforward
==============

.. contents::

Overview
========

Comman Kang  sent me: ::

  Hello jan.

       I've made something rough but similar to mod_extract_forwarded for
  Apache.  This module will extract the client's "real" ip from
  X-Forwarded-For header which is added by squid or other proxies. It might be
  useful for servers behind reverse proxy servers.

       However, this module is causing segfault with mod_ssl or
  $HTTP{''socket"} directive,  crashing in config_check_cond while patching
  connection ,  I do not understand architecture of the lighttpd well, does it
  need to call patch_connection in either handle_request_done and
  connection_reset ?

Lionel Elie Mamane  improved the patch: ::

    I've taken lighttpd-1.4.10-mod_extforward.c from the wiki and I've
  extended it. Here is the result.

  Major changes:

   - IPv6 support

   - Fixed at least one segfault with SERVER['socket']

   - Arrange things so that a url.access-deny under scope of a
     HTTP['remoteip'] condition works well :)

  I've commented the code in some places, mostly where I wasn't sure
  what was going on, or I didn't see what the original author meant to
  do.

Options
=======

extforward.forwarder
  Sets trust level of proxy IP's.

  Default: empty

  Example: ::

    extforward.forwarder = ("10.0.0.232" => "trust")

  will translate ip addresses coming from 10.0.0.232 to real ip addresses extracted from "X-Forwarded-For" or "Forwarded-For" HTTP request header.

extforward.headers
  Sets headers to search for finding the originl addresses.

  Example (for use with a Zeus ZXTM loadbalancer): ::

    extforward.headers = ("X-Cluster-Client-Ip")

  Default: empty, results in searching for "X-Forwarded-For" and "Forwarded-For"

Note
=======

The effect of this module is variable on $HTTP["remotip"] directives and other module's remote ip dependent actions.
Things done by modules before we change the remoteip or after we reset it will match on the proxy's IP.
Things done in between these two moments will match on the real client's IP.
The moment things are done by a module depends on in which hook it does things and within the same hook
on whether they are before/after us in the module loading order
(order in the server.modules directive in the config file).

Tested behaviours:

  mod_access: Will match on the real client.

  mod_accesslog:
   In order to see the "real" ip address in access log ,
   you'll have to load mod_extforward after mod_accesslog.
   like this: ::

    server.modules  = (
       .....
       mod_accesslog,
       mod_extforward
    )

Samples
=======

Trust proxy 10.0.0.232 and 10.0.0.232 ::

  extforward.forwarder = (
     "10.0.0.232" => "trust",
     "10.0.0.233" => "trust",
  )

Trust all proxies  (NOT RECOMMENDED!) ::

  extforward.forwarder = ( "all" => "trust")

Note that "all" has precedence over specific entries, so "all except" setups will not work.

  handling performance issues in lighttpd

.. meta::
  :keywords: lighttpd, performance

.. contents:: Table of Contents

Description
===========

Performance Issues
------------------

lighttpd is optimized into varying directions. The most important direction is
performance. The operation system has two major facilities to help lighttpd
a deliver its best performance.

HTTP Keep-Alive
---------------

Disabling keep-alive might help your server if you suffer from a large
number of open file descriptors.

The defaults for the server are: ::

  server.max-keep-alive-requests = 128
  server.max-keep-alive-idle = 30
  server.max-read-idle = 60
  server.max-write-idle = 360

handling 128 keep-alive requests in a row on a single connection, waiting 30 seconds
before an unused keep-alive connection gets dropped by lighttpd.

If you handle several connections at once under a high load (let's assume 500 connections
in parallel for 24h) you might run into the out-of-fd problem described below. ::

  server.max-keep-alive-requests = 4
  server.max-keep-alive-idle = 4

would release the connections earlier and would free file descriptors without a
detrimental performance loss.

Disabling keep-alive completely is the last resort if you are still short on file descriptors: ::

  server.max-keep-alive-requests = 0

Event Handlers
--------------

The first one is the Event Handler which takes care of notifying the server
that one of the connections is ready to send or receive. As you can see,
every OS has at least the select() call which has some limitations.

============ ========== ===============
OS           Method     Config Value
============ ========== ===============
all          select     select
Unix         poll       poll
Linux 2.4+   rt-signals linux-rtsig
Linux 2.6+   epoll      linux-sysepoll
Solaris      /dev/poll  solaris-devpoll
FreeBSD, ... kqueue     freebsd-kqueue
============ ========== ===============


For more information on this topic take a look at http://www.kegel.com/c10k.html

Configuration
`````````````

The event handler can be set by specifying the 'Config Value' from above
in the ``server.event-handler`` variable

e.g.: ::

  server.event-handler = "linux-sysepoll"

Network Handlers
----------------

The basic network interface for all platforms at the syscalls read() and
write(). Every modern OS provides its own syscall to help network servers
transfer files as fast as possible.

If you want to send out a file from the webserver, it doesn't make any sense
to copy the file into the webserver just to write() it back into a socket
in the next step.

sendfile() minimizes the work in the application and pushes a file directly
into the network card (ideally).

lighttpd supports all major platform-specific calls:

========== ==========
OS         Method
========== ==========
all        write
Unix       writev
Linux 2.4+ sendfile
Linux 2.6+ sendfile64
Solaris    sendfilev
FreeBSD    sendfile
========== ==========

The best backend is selected at compile time. In case you want to use
another backend set: ::

  server.network-backend = "writev"

You can find more information about network backend in:

  http://blog.lighttpd.net/articles/2005/11/11/optimizing-lighty-for-high-concurrent-large-file-downloads


Max Connections
---------------

As lighttpd is a single-threaded server, its main resource limit is the
number of file descriptors, which is set to 1024 by default (on most systems).

If you are running a high-traffic site you might want to increase this limit
by setting ::

  server.max-fds = 2048

This only works if lighttpd is started as root.

Out-of-fd condition
-------------------

Since file descriptors are used for TCP/IP sockets, files and directories,
a simple request for a PHP page might result in using 3 file descriptors:

1. the TCP/IP socket to the client
2. the TCP/IP and Unix domain socket to the FastCGI process
3. the filehandle to the file in the document root to check if it exists

If lighttpd runs out of file descriptors, it will stop accepting new
connections for awhile to use the existing file descriptors to handle the
currently-running requests.

If more than 90% of the file descriptors are used then the handling of new
connections is disabled. If it drops below 80% again new connections will
be accepted again.

Under some circumstances you will see ::

  ... accept() failed: Too many open files

in the error log. This tells you there were too many new requests at once
and lighttpd could not disable the incoming connections soon enough. The
connection was dropped and the client received an error message like 'connection
failed'. This is very rare and might only occur in test setups.

Increasing the ``server.max-fds`` limit will reduce the probability of this
problem.

stat() cache
============

A stat(2) can be expensive; caching it saves time and context switches.

Instead of using stat() every time to check for the existence of a file
you can stat() it once and monitor the directory the file is in for
modifications. As long as the directory doesn't change, the files in it
must all still be the same.

With the help of FAM or gamin you can use kernel events to assure that
your stat cache is up to date. ::

  server.stat-cache-engine = "fam"   # either fam, simple or disabled


Platform-Specific Notes
=======================

Linux
-----

For Linux 2.4.x you should think about compiling lighttpd with the option
``--disable-lfs`` to disable the support for files larger than 2GB. lighttpd will
fall back to the ``writev() + mmap()`` network calls which is ok, but not as
fast as possible but support files larger than 2GB.

Disabling the TCP options reduces the overhead of each TCP packet and might
help to get the last few percent of performance out of the server. Be aware that
disabling these options most likely decreases performance for high-latency and lossy
links.

- net.ipv4.tcp_sack = 0
- net.ipv4.tcp_timestamps = 0

Increasing the TCP send and receive buffers will increase the performance a
lot if (and only if) you have a lot of large files to send.

- net.ipv4.tcp_wmem = 4096 65536 524288
- net.core.wmem_max = 1048576

If you have a lot of large file uploads, increasing the receive buffers will help.

- net.ipv4.tcp_rmem = 4096 87380 524288
- net.core.rmem_max = 1048576

Keep in mind that every TCP connection uses the configured amount of memory for socket
buffers. If you've got many connections this can quickly drain the available memory.

See http://www.acc.umu.se/~maswan/linux-netperf.txt for more information on these parameters.

FreeBSD
-------

On FreeBSD you might gain some performance by enabling accept filters. Just
compile your kernel with: ::

  options   ACCEPT_FILTER_HTTP

For more ideas about tuning FreeBSD read: tuning(7)

Reducing the recvspace should always be ok if the server only handles HTTP
requests without large uploads. Increasing the sendspace would reduce the
system load if you have a lot of large files to be sent, but keep in mind that
you have to provide the memory in the kernel for each connection. 1024 * 64KB
would mean 64MB of kernel RAM. Keep this in mind.

- net.inet.tcp.recvspace = 4096

  This is a short summary of the state-engine which is driving the lighttpd
  webserver. It describes the basic concepts and the way the different parts
  of the server are connected.

.. meta::
  :keywords: lighttpd, state-engine

.. contents:: Table of Contents

Description
===========

States
------

The state-engine is currently made of 11 states which are walk-through on
the way each connection. Some of them are specific for a special operation
and some may never be hit at all.

:connect:
  waiting for a connection
:reqstart:
  init the read-idle timer
:read:
  read http-request-header from network
:reqend:
  parse request
:readpost:
  read http-request-content from network
:handlereq:
  handle the request internally (might result in sub-requests)
:respstart:
  prepare response header
:write:
  write response-header + content to network
:respend:
  cleanup environment, log request
:error:
  reset connection (incl. close())
:close:
  close connection (handle lingering close)

.. image:: state.png

A simple GET request (green path)
---------------------------------

The connection is idling in the 'connect' state waiting for a connection.
As soon as the connection is set up we init the read-timer in 'reqstart'
and start to read data from the network. As soon as we get the
HTTP-request terminator (CRLFCRLF) we forward the header to the parser.

The parsed request is handled by 'handlereq' and as soon as a decision out
the request is made it is sent to 'respstart' to prepare the
HTTP-response header. In the 'write' state the prepare content is sent out
to the network. When everything is sent 'respend' is entered to log the
request and cleanup the environment. After the close() call the connection
is set back to the 'connect' state again.

Keep-Alive (blue path)
----------------------

The Keep-Alive handling is implemented by going from the 'respend'
directly to 'reqstart' without the close() and the accept() calls.

POST requests (grey path)
-------------------------

As requests might contain a request-body the state 'readpost' entered as
soon as the header is parsed and we know how much data we expect.

Pipelining
----------

HTTP/1.1 supportes pipelining (sending multiple requests without waiting
for the response of the first request). This is handled transparently by
the 'read' state.

Unexpected errors (red path)
----------------------------

For really hard errors we use the 'error' state which resets the
connection and can be call from every state. It is only use if there is no
other way to handle the issue (e.g. client-side close of the connection).
If possible we should use http-status 500 ('internal server error') and
log the issue in the errorlog.

If we have to take care of some data which is coming in after we ran into
the error condition the 'close' state is used the init a half-close and
read all the delay packet from the network.

Sub-Requests (lightblue)
------------------------

The FastCGI, CGI, ... intergration is done by introducing a loop in
'handlereq' to handle all aspect which are neccesary to find out what has
to be sent back to the client.

------------------
Module: mod_magnet
------------------



.. contents:: Table of Contents

Requirements
============

:Version: lighttpd 1.4.12 or higher
:Packages: lua >= 5.1

Overview
========

mod_magnet is a module to control the request handling in lighty. 

.. note::

  Keep in mind that the magnet is executed in the core of lighty. EVERY long-running operation is blocking 
  ALL connections in the server. You are warned. For time-consuming or blocking scripts use mod_fastcgi and friends.

For performance reasons mod_magnet caches the compiled script. For each script-run the script itself is checked for 
freshness and recompile if neccesary.


Installation
============

mod_magnet needs a lighty which is compiled with the lua-support ( --with-lua). Lua 5.1 or higher are required by
the module. Use "--with-lua=lua5.1" to install on Debian and friends. ::

  server.modules = ( ..., "mod_magnet", ... )

Options
=======

mod_magnet can attract a request in several stages in the request-handling. 

* either at the same level as mod_rewrite, before any parsing of the URL is done
* or at a later stage, when the doc-root is known and the physical-path is already setup

It depends on the purpose of the script which stage you want to intercept. Usually you want to use
the 2nd stage where the physical-path which relates to your request is known. At this level you
can run checks against lighty.env["physical.path"].

::

  magnet.attract-raw-url-to = ( ... )
  magnet.attract-physical-path-to = ( ... )

You can define multiple scripts when separated by a semicolon. The scripts are executed in the specified 
order. If one of them a returning a status-code, the following scripts will not be executed.

Tables
======

Most of the interaction between between mod_magnet and lighty is done through tables. Tables in lua are hashes (Perl), dictionaries (Java), arrays (PHP), ...

Request-Environment
-------------------

Lighttpd has its internal variables which are exported as read/write to the magnet. 

If "http://example.org/search.php?q=lighty" is requested this results in a request like ::

  GET /search.php?q=lighty HTTP/1.1
  Host: example.org

When you are using ``attract-raw-url-to`` you can access the following variables:

* parts of the request-line

 * lighty.env["request.uri"] = "/search.php?q=lighty"

* HTTP request-headers

  * lighty.request["Host"] = "example.org"

Later in the request-handling, the URL is splitted, cleaned up and turned into a physical path name:

* parts of the URI

 * lighty.env["uri.path"] = "/search.php"
 * lighty.env["uri.path-raw"] = "/search.php"
 * lighty.env["uri.scheme"] = "http"
 * lighty.env["uri.authority"] = "example.org"
 * lighty.env["uri.query"] = "q=lighty"

* filenames, pathnames

 * lighty.env["physical.path"] = "/my-docroot/search.php"
 * lighty.env["physical.rel-path"] = "/search.php"
 * lighty.env["physical.doc-root"] = "/my-docroot"

All of them are readable, not all of the are writable (or don't have an effect if you write to them). 

As a start, you might want to use those variables for writing: ::

  -- 1. simple rewriting is done via the request.uri
  lighty.env["request.uri"] = ... 
  return lighty.RESTART_REQUEST

  -- 2. changing the physical-path
  lighty.env["physical.path"] = ...

  -- 3. changing the query-string
  lighty.env["uri.query"] = ...

Response Headers
----------------

If you want to set a response header for your request, you can add a field to the lighty.header[] table: ::

  lighty.header["Content-Type"] = "text/html"

Sending Content
===============

You can generate your own content and send it out to the clients. ::

  lighty.content = { "
", { filename = "/etc/passwd" }, "
" }
  lighty.header["Content-Type"] = "text/html"

  return 200

The lighty.content[] table is executed when the script is finished. The elements of the array are processed left to right and the elements can either be a string or a table. Strings are included AS IS into the output of the request.

* Strings

  * are included as is

* Tables

  * filename = "" is required
  * offset =  [default: 0]
  * length =  [default: size of the file - offset]

Internally lighty will use the sendfile() call to send out the static files at full speed.

Status Codes
============

You might have seen it already in other examples: In case you are handling the request completly in the magnet you
can return your own status-codes. Examples are: Redirected, Input Validation, ... ::

  if (lighty.env["uri.scheme"] == "http") then
    lighty.header["Location"] = "https://" .. lighty.env["uri.authority"] .. lighty.env["request.uri"]
    return 302
  end

You every number above and equal to 100 is taken as final status code and finishes the request. No other modules are 
executed after this return.

A special return-code is lighty.RESTART_REQUEST (currently equal to 99) which is usually used in combination with 
changing the request.uri in a rewrite. It restarts the splitting of the request-uri again.

If you return nothing (or nil) the request-handling just continues.

Debugging
=========

To easy debugging we overloaded the print()-function in lua and redirect the output of print() to the error-log. ::

  print("Host: " .. lighty.request["Host"])
  print("Request-URI: " .. lighty.env["request.uri"])


Examples
========

Sending text-files as HTML
--------------------------

This is a bit simplistic, but it illustrates the idea: Take a text-file and cover it in a 
 tag.

Config-file ::

  magnet.attract-physical-path-to = server.docroot + "/readme.lua"

readme.lua ::

  lighty.content = { "
", { filename = "/README" }, "
" }
  lighty.header["Content-Type"] = "text/html"
  
  return 200

Maintainance pages
------------------

Your side might be on maintainance from time to time. Instead of shutting down the server confusing all
users, you can just send a maintainance page.

Config-file ::

  magnet.attract-physical-path-to = server.docroot + "/maintainance.lua"

maintainance.lua ::

  require "lfs"

  if (nil == lfs.attributes(lighty.env["physical.doc-root"] .. "/maintainance.html")) then
    lighty.content = ( lighty.env["physical.doc-root"] .. "/maintainance.html" )

    lighty.header["Content-Type"] = "text/html"

    return 200
  end

mod_flv_streaming
-----------------

Config-file ::

  magnet.attract-physical-path-to = server.docroot + "/flv-streaming.lua"

flv-streaming.lua::

  if (lighty.env["uri.query"]) then
    -- split the query-string
    get = {}
    for k, v in string.gmatch(lighty.env["uri.query"], "(%w+)=(%w+)") do
      get[k] = v
    end

    if (get["start"]) then
      -- missing: check if start is numeric and positive

      -- send te FLV header + a seek into the file
      lighty.content = { "FLV\x1\x1\0\0\0\x9\0\0\0\x9", 
         { filename = lighty.env["physical.path"], offset = get["start"] } }
      lighty.header["Content-Type"] = "video/x-flv"

      return 200
    end
  end

  
selecting a random file from a directory
----------------------------------------

Say, you want to send a random file (ad-content) from a directory. 

To simplify the code and to improve the performance we define:

* all images have the same format (e.g. image/png)
* all images use increasing numbers starting from 1
* a special index-file names the highest number

Config ::

  server.modules += ( "mod_magnet" )
  magnet.attract-physical-path-to = "random.lua"

random.lua ::

  dir = lighty.env["physical.path"]

  f = assert(io.open(dir .. "/index", "r"))
  maxndx = f:read("*all")
  f:close()

  ndx = math.random(maxndx)

  lighty.content = { { filename = dir .. "/" .. ndx }}
  lighty.header["Content-Type"] = "image/png"

  return 200

denying illegal character sequences in the URL
----------------------------------------------

Instead of implementing mod_security, you might just want to apply filters on the content
and deny special sequences that look like SQL injection. 

A common injection is using UNION to extend a query with another SELECT query.

::

  if (string.find(lighty.env["request.uri"], "UNION%s")) then
    return 400
  end

Traffic Quotas
--------------

If you only allow your virtual hosts a certain amount for traffic each month and want to 
disable them if the traffic is reached, perhaps this helps: ::

  host_blacklist = { ["www.example.org"] = 0 }

  if (host_blacklist[lighty.request["Host"]]) then
    return 404
  end

Just add the hosts you want to blacklist into the blacklist table in the shown way.

Complex rewrites
----------------

If you want to implement caching on your document-root and only want to regenerate 
content if the requested file doesn't exist, you can attract the physical.path: ::

  magnet.attract-physical-path-to = ( server.document-root + "/rewrite.lua" )

rewrite.lua ::

  require "lfs"

  attr = lfs.attributes(lighty.env["physical.path"])

  if (not attr) then
    -- we couldn't stat() the file for some reason
    -- let the backend generate it

    lighty.env["uri.path"] = "/dispatch.fcgi"
    lighty.env["physical.rel-path"] = lighty.env["uri.path"]
    lighty.env["physical.path"] = lighty.env["physical.doc-root"] .. lighty.env["physical.rel-path"]
  fi

luafilesystem
+++++++++++++

We are requiring the lua-module 'lfs' (http://www.keplerproject.org/luafilesystem/). 

I had to compile lfs myself for lua-5.1 which required a minor patch as compat-5.1 is not needed::

  $ wget http://luaforge.net/frs/download.php/1487/luafilesystem-1.2.tar.gz
  $ wget http://www.lighttpd.net/download/luafilesystem-1.2-lua51.diff
  $ gzip -cd luafilesystem-1.2.tar.gz | tar xf -
  $ cd luafilesystem-1.2
  $ patch -ls -p1 < ../luafilesystem-1.2-lua51.diff
  $ make install

It will install lfs.so into /usr/lib/lua/5.1/ which is where lua expects the extensions on my system.

SuSE and Gentoo are known to have their own lfs packages and don't require a compile.

Usertracking
------------

... or how to store data globally in the script-context:

Each script has its own script-context. When the script is started it only contains the lua-functions
and the special lighty.* name-space. If you want to save data between script runs, you can use the global-script
context:

::

  if (nil == _G["usertrack"]) then
    _G["usertrack"] = {}
  end
  if (nil == _G["usertrack"][lighty.request["Cookie"]]) then
    _G["usertrack"][lighty.request["Cookie"]]
  else 
    _G["usertrack"][lighty.request["Cookie"]] = _G["usertrack"][lighty.request["Cookie"]] + 1
  end

  print _G["usertrack"][lighty.request["Cookie"]]

The global-context is per script. If you update the script without restarting the server, the context will still be maintained.

Counters
--------

mod_status support a global statistics page and mod_magnet allows to add and update values in the status page:

Config ::

  status.statistics-url = "/server-counters"
  magnet.attract-raw-url-to = server.docroot + "/counter.lua"

counter.lua ::

  lighty.status["core.connections"] = lighty.status["core.connections"] + 1

Result::

  core.connections: 7
  fastcgi.backend.php-foo.0.connected: 0
  fastcgi.backend.php-foo.0.died: 0
  fastcgi.backend.php-foo.0.disabled: 0
  fastcgi.backend.php-foo.0.load: 0
  fastcgi.backend.php-foo.0.overloaded: 0
  fastcgi.backend.php-foo.1.connected: 0
  fastcgi.backend.php-foo.1.died: 0
  fastcgi.backend.php-foo.1.disabled: 0
  fastcgi.backend.php-foo.1.load: 0
  fastcgi.backend.php-foo.1.overloaded: 0
  fastcgi.backend.php-foo.load: 0

Porting mod_cml scripts
-----------------------

mod_cml got replaced by mod_magnet.

A CACHE_HIT in mod_cml::
 
  output_include = { "file1", "file2" } 

  return CACHE_HIT

becomes::

  content = { { filename = "/path/to/file1" }, { filename = "/path/to/file2"} }

  return 200

while a CACHE_MISS like (CML) ::

  trigger_handler = "/index.php"

  return CACHE_MISS

becomes (magnet) ::

  lighty.env["request.uri"] = "/index.php"

  return lighty.RESTART_REQUEST

connect, write and read may need to wait for an fdevent. That's the reason
for the loop in the state-diagram.

CML (Cache Meta Language)
=========================

---------------
Module: mod_cml
---------------

:Author: Jan Kneschke
:Date: $Date: 2004/11/03 22:26:05 $
:Revision: $Revision: 1.2 $

:abstract:
  CML is a Meta language to describe the dependencies of a page at one side and building a page from its fragments on the other side using LUA.

.. meta::
  :keywords: lighttpd, cml, lua

.. contents:: Table of Contents

Description
===========

CML (Cache Meta Language) wants to solves several problems:

 * dynamic content needs caching to perform
 * checking if the content is dirty inside of the application is usually more expensive than sending out the cached data
 * a dynamic page is usually fragmented and the fragments have different livetimes
 * the different fragements can be cached independently

Cache Decision
--------------

A simple example should show how to a content caching the very simple way in PHP.

jan.kneschke.de has a very simple design:

 * the layout is taken from a template in templates/jk.tmpl
 * the menu is generated from a menu.csv file
 * the content is coming from files on the local directory named content-1, content-2 and so on

The page content is static as long non of the those tree items changes. A change in the layout
is affecting all pages, a change of menu.csv too, a change of content-x file only affects the
cached page itself.

If we model this in PHP we get: ::

   $v) {
      if (isset($v["file"]) &&
          filemtime($v["file"]) > $cachemtime) {
        return 0;
      }
    }

    if (filemtime("/menu/menu.csv") > $cachemtime) {
      return 0;
    }
    if (filemtime("/templates/jk.tmpl") > $cachemtime) {
      return 0;
    }
  }

  if (is_cachable(...), $cachefile) {
    readfile($cachefile);
    exit();
  } else {
    # generate content and write it to $cachefile
  }
  ?>

Quite simple. No magic involved. If the one of the files is new than the cached
content, the content is dirty and has to be regenerated.

Now let take a look at the numbers:

 * 150 req/s for a Cache-Hit
 * 100 req/s for a Cache-Miss

As you can see the increase is not as good as it could be. The main reason as the overhead
of the PHP interpreter to start up (a byte-code cache has been used here).

Moving these decisions out of the PHP script into a server module will remove the need
to start PHP for a cache-hit.

To transform this example into a CML you need 'index.cml' in the list of indexfiles
and the following index.cml file: ::

  output_contenttype = "text/html"

  b = request["DOCUMENT_ROOT"]
  cwd = request["CWD"]

  output_include = { b .. "_cache.html" }

  trigger_handler = "index.php"

  if file_mtime(b .. "../lib/php/menu.csv") > file_mtime(cwd .. "_cache.html") or
     file_mtime(b .. "templates/jk.tmpl")   > file_mtime(cwd .. "_cache.html") or
     file_mtime(b .. "content.html")        > file_mtime(cwd .. "_cache.html") then
     return CACHE_MISS
  else
     return CACHE_HIT
  end

Numbers again:

 * 4900 req/s for Cache-Hit
 *  100 req/s for Cache-Miss

Content Assembling
------------------

Sometimes the different fragment are already generated externally. You have to cat them together: ::

  

We we can do the same several times faster directly in the webserver.

Don't forget: Webserver are built to send out static content, that is what they can do best.

The index.cml for this looks like: ::

  output_contenttype = "text/html"

  cwd = request["CWD"]

  output_include = { cwd .. "head.html",
                     cwd .. "menu.html",
                     cwd .. "spacer.html",
                     cwd .. "db-content.html",
                     cwd .. "spacer2.html",
                     cwd .. "news.html",
                     cwd .. "footer.html" }

  return CACHE_HIT

Now we get about 10000 req/s instead of 600 req/s.

Power Magnet
------------

Next to all the features about Cache Decisions CML can do more. Starting
with lighttpd 1.4.9 a power-magnet was added which attracts each request
and allows you to manipulate the request for your needs.

We want to display a maintainance page by putting a file in a specified
place:

We enable the power magnet: ::

  cml.power-magnet  = "/home/www/power-magnet.cml"

and create /home/www/power-magnet.cml with: ::

  dr = request["DOCUMENT_ROOT"]

  if file_isreg(dr .. 'maintainance.html') then
    output_include = { 'maintainance.html' }
    return CACHE_HIT
  end

  return CACHE_MISS

For each requested file the /home/www/power-magnet.cml is executed which
checks if maintainance.html exists in the docroot and displays it
instead of handling the usual request.

Another example, create thumbnail for requested image and serve it instead
of sending the big image: ::

  ## image-url is /album/baltic_winter_2005.jpg
  ## no params -> 640x480 is served
  ## /album/baltic_winter_2005.jpg/orig for full size
  ## /album/baltic_winter_2005.jpg/thumb for thumbnail

  dr = request["DOCUMENT_ROOT"]
  sn = request["SCRIPT_NAME"]

  ## to be continued :) ...

  trigger_handler = '/gen_image.php'

  return CACHE_MISS


Installation
============

You need `lua `_ and should install `libmemcache-1.3.x `_ and have to configure lighttpd with: ::

  ./configure ... --with-lua --with-memcache

To use the plugin you have to load it: ::

   server.modules = ( ..., "mod_cml", ... )

Options
=======

:cml.extension:
  the file extension that is bound to the cml-module
:cml.memcache-hosts:
  hosts for the memcache.* functions
:cml.memcache-namespace:
  (not used yet)
:cml.power-magnet:
  a cml file that is executed for each request

Language
========

The language used for CML is provided by `LUA `_.

Additionally to the functions provided by lua mod_cml provides: ::

  tables:

  request
    - REQUEST_URI
    - SCRIPT_NAME
    - SCRIPT_FILENAME
    - DOCUMENT_ROOT
    - PATH_INFO
    - CWD
    - BASEURI

  get
    - parameters from the query-string

  functions:
  string md5(string)
  number file_mtime(string)
  string memcache_get_string(string)
  number memcache_get_long(string)
  boolean memcache_exists(string)


What ever your script does, it has to return either CACHE_HIT or CACHE_MISS.
It case a error occures check the error-log, the user will get a error 500. If you don't like
the standard error-page use ``server.errorfile-prefix``.

Server Status
=============

Module: mod_status

:Revision: $Revision: 1.2 $

:abstract:
  mod_status displays the server's status and configuration

.. meta::
  :keywords: lighttpd, server status

.. contents:: Table of Contents

Description
===========

The server status module generates the status overview of the webserver. The
information covers:

- uptime
- average throughput
- current throughput
- active connections and their state


We need to load the module first. ::

  server.modules = ( ..., "mod_ssi", ... )

By default the status page is disabled to hide internal information from
unauthorized users. ::

  status.status-url = "/server-status"

If you want to open the status page just for users from the local network
cover it in a conditional. ::

  $HTTP["remoteip"] == "10.0.0.0/8" {
    status.status-url = "/server-status"
  }

Or require authorization: ::

  auth.require = ( "/server-status" =>
    ( "realm" ... ) )


Please note that when using the server.max-worker directive, the stati of the
childs are not combined yet, so you're going to see different stats with each
request.


Output Format
-------------

By default a nice looking HTML page is generated. If you append ?auto to the
status-url you can get a text version which is simpler to parse. ::

  Total Accesses: 1234
  Total kBytes: 1043
  Uptime: 1234
  BusyServers: 123

Total Accesses is the number of handled requests, kBytes the overall outgoing
traffic, Uptime the uptime in seconds and BusyServers the number of currently
active connections.

The naming is kept compatible to Apache even if we have another concept and
don't start new servers for each connection.


Options
=======

status.status-url

  relative URL which is used to retrieve the status-page

  Default: unset

  Example: status.status-url = "/server-status"

status.enable-sort

  add JavaScript which allows client-side sorting for the connection overview

  Default: enable

status.config-url

  relative URL for the config page which displays the loaded modules

  Default: unset

  Example: status.config-url = "/server-config"

status.statistics-url

  relative URL for a plain-text page containing the internal statistics

  Default: unset

  Example: status.statistics-url = "/server-statistics"

  url rewrite

.. meta::
  :keywords: lighttpd, rewrite

.. contents:: Table of Contents

Description
===========

internal redirects, url rewrite

Options
=======

url.rewrite-once
  rewrites a set of URLs interally in the webserver BEFORE they are handled.

  e.g. ::

    url.rewrite-once = ( "" => "" )

url.rewrite-repeat
  rewrites a set of URLs interally in the webserver BEFORE they are handled

  e.g. ::

    url.rewrite-repeat = ( "" => "" )

The options ``url.rewrite`` and ``url.rewrite-final`` were mapped to ``url.rewrite-once``
in 1.3.16.

Warning
=======

Do NOT use mod_rewrite to protect specific urls, as the original url passed from the client
is matched against your rules, for example strings like "/abc/../xyz%2f/path".

Examples
========

The regex is matching the full REQUEST_URI which is supplied by the user including
query-string.::

  url.rewrite-once = ( "^/id/([0-9]+)$" => "/index.php?id=$1",
                       "^/link/([a-zA-Z]+)" => "/index.php?link=$1" )



  # the following example, is, however just simulating vhost by rewrite
  # * you can never change document-root by mod_rewrite
  # use mod_*host instead to make real mass-vhost

  # request:        http://any.domain.com/url/
  # before rewrite: REQUEST_URI="/www/htdocs/url/"
  # and DOCUMENT_ROOT="/www/htdocs/" %0="www.domain.com" $1="url/"
  # after rewrite:  REQUEST_URI="/www/htdocs/domain.com/url/"
  # still, you have DOCUMENT_ROOT=/www/htdocs/

  server.document-root = "/www/htdocs/"
  $HTTP["host"] =~ "^.*\.([^.]+\.com)$" {
    url.rewrite-once = ( "^/(.*)" => "/%0/$1" )
  }

Description
===========

The access module is used to deny access to files with given trailing path names.

Options
=======

url.access-deny
  Denies access to all files with any of given trailing path names.

  Default: empty

  Example: ::

    url.access-deny = ( "~", ".inc")

  will deny access to all files ended with a diacritical mark (~) or .inc
  such as example~ or example.inc.  A trailing diacritical mark is often
  used by editors for backup files.  And the .inc extension is often used
  for include files with code.

  This document tries to track the requested features and
  the release when they have been implemented.

.. meta::
  :keywords: lighttpd, features

.. contents:: Table of Contents

Description
===========

The document was inspired by a mail from David Phillips:

http://marc.theaimsgroup.com/?l=thttpd&m=108051453226692&w=2

It is used to see what is still missing and what is already done. ::

  zell@zell.best.vwh.net writes:

  If you think it compares to Zeus, then you've obviously never used Zeus.

  lighttpd is currently the only non-blocking open source web server to
  support FastCGI responders and that's worthwhile.

  The documentation is lacking.  Comments in the configuration file do not
  make up for a complete manual.

Constantly improving. ::

  The configuration syntax is overly complex, like Apache.  There is no .htaccess
  support.

.htaccess support is not planed yet. ::

  There is only one server.  You cannot have a separate configuration for each
  virtual server.  This would seem to be especially problematic when doing
  SSL.

Works since 1.3.0. ::

  There is no SSI support.  Zeus has full recursive SSI support.  Output from
  a FastCGI program can get run through the SSI interpreter.  SSI can also do
  virtual includes recursively.

SSI works since 1.2.4. ::

  Request logging is not configurable.  Zeus supports fully configurable
  access logging, plus a binary version of CLF that save space.

1.2.6 adds Apache-like logfile config. ::

  Access control only allows authentication via username and password.  There
  is no way to allow or deny based in IP address.

planed for 1.3.x ::

  The request rewriting appears to only allow regex substitutions.  Zeus has a
  simple, yet powerful, request rewrite language.



  There is no support for FastCGI authorizers.  These are very useful for high
  traffic sites that require complex authentication schemes or that store
  authorization information in a central database.

since 1.1.9. ::

  There is no bandwidth throttling support.  Zeus does bandwidth throttling
  correctly (i.e. unlike past versions of thttpd) and can throttle on a
  per-subserver (thttpd-style virtual hosts) basis.

since 1.3.8. ::

  There is no ISAPI support.  ISAPI is an elegant, open API that allows
  modification of web server behavior.  While it isn't strictly necessary for
  an open source web server, it nice to have a documented, consistent API,
  rather than having to manually patch the server.

If someone requests it it might be implemented. ::

  There is no web based interface.  Zeus has a complete web based interface
  for everything, including a powerful feature of configuring multiple virtual
  servers at once.

That is something that should be a special feature of Zeus. :) ::

  There is no support for mapping certain URLs to specific filesystem paths.

since 1.2.6 ::

  There is no referring checking.  This is incredibly important to prevent
  hotlinking of bandwidth intensive media types (images, movies, etc.).

we have something better: mod_secdownload. And if someone wants referer
checking we have a condition in the config for it since 1.2.9 ::

  Zeus has a lot of features that lighttpd doesn't have, but I only mentioned
  the ones I care about and use.
