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

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

A BNF like notation: ::

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

Example
-------

::

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

1. TCP port
   server.port = 80

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

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

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

1. 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).

::

<field> <operator> <value> {
    ...
    <field> <operator> <value> {
      ... nesting: match only when parent match
    }
  }
  else <field> <operator> <value> {
    ... the "else if" block
  }

where <field> is one of one of the following:

$HTTP["cookie"]
match on cookie
$HTTP["host"]
match on host
$HTTP["useragent"]
match on useragent
$HTTP["referer"]
match on referer
$HTTP["url"]
match on url. If there are nested blocks, this must be the most inner block.
$HTTP["querystring"]
match on querystring, eg, after the ? in this type url: index.php?module=images..
$HTTP["remoteip"]
match on the remote IP or a remote Network (Warning: doesn't work with IPv6 enabled)
$HTTP["scheme"] (Introduced in version 1.4.19)
match on the scheme used by the incoming connection. This is either "http" or "https".
$SERVER["socket"]
match on socket. Value must be on the format "ip:port" where ip is an IP address and
port a port number, or ":port" to match port only. 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.
$PHYSICAL["path"] (Introduced in version 1.5.0)
match on the mapped physical path of the file / cgi script to be served.
$PHYSICAL["existing-path"] (Introduced in version 1.5.0)
match on the mapped physical path of the file / cgi script to be served
only if such a file exists on the local filesystem.

<operator> is one of:

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

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

Example
-------

::

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

1. handle virtual hosting
2. 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/"
   }

1. 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/" 
  }

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

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

1. deny the access to www.example.org to all user which
2. 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 = ( "" )
   }
   }

1. Allow only 200.19.1.5 and 210.45.2.7 to
2. have access to www.example.org/admin/
   $HTTP["host"] == "www.example.org" {
   #!~ is a perl style regular expression not match
   $HTTP["remoteip"] !~ "^(200\.19\.1\.5|210\.45\.2\.7)$" {
   $HTTP["url"] =~ "^/admin/" {
   url.access-deny = ( "" )
   }
   }
   }

Troubleshooting
---------------

If you're not running on the default port, $HTTP["host"] will have the port appended to it, so regular expressions ending in "$" (without allowing for a port) won't match. To match with or without a port, change "(^{|\.)example\.org$" to "(}|\.)example\.org(\:[0-9]*)?$"

advanced usage ==============
check the blog:
http://blog.lighttpd.net/articles/2005/05/07/advanced-configuration-in-up-upcoming-1-4-x

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 environment 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 a 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 = "..."
