 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 
 ------- 

 :: 
  
   # 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). 

 :: 

   <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 
 $HTTP["remoteip"] 
   match on the remote IP or a remote Network 
 $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. 

 <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 
 ------- 

 :: 

   # 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 = "..." 

 Options 
 ======= 

 server module 
 ------------- 

 main sections 
 ````````````` 

 server.document-root 
   document-root of the webserver 

   This variable has the specified as it will be used for all requests 
   without a Host: header and for all with a know hostname which you 
   might have specified with one of the above conditionals. 

   Default: no default, required 
  
 server.bind 
   IP address, hostname or absolute path to the unix-domain socket the server 
   listen on. 
  
   Default: bind to all interfaces 

   Example: :: 

     server.bind = "127.0.0.1" 
     server.bind = "www.example.org" 
     server.bind = "/tmp/lighttpd.socket" 
  
 server.port 
   tcp-port to bind the server to 
  
 .. note:: port belows 1024 require root-permissions 
  
   Default: 80 (443 if ssl is enabled) 
  
 server.use-ipv6 
   bind to the IPv6 socket 

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

   Default: lighttpd <current-version> 
  
 server.errorlog 
   pathname of the error-log 
  
   Default: either STDERR or ``server.errorlog-use-syslog`` 
  
 server.errorlog-use-syslog 
   send errorlog to syslog 
  
   Default: disabled 
  
 server.chroot 
   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 
   allow to follow-symlinks 
  
   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 

 debugging 
 ````````` 

 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 
  
   e.g.: :: 
  
     mimetype.assign     = ( ".png"    => "image/png",  
                           ".jpg"    => "image/jpeg", 
                           ".jpeg" => "image/jpeg", 
			   ".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

 debug.log-request-header 
   default: disabled  
  
 debug.log-response-header
