{{{ #!rst =============================================== Controlling the Expiration of Content in Caches =============================================== ------------------ Module: mod_expire ------------------ .. meta:: :keywords: lighttpd, expire .. contents:: Table of Contents Description =========== mod_expire controls the Expire header in the Response Header of HTTP/1.0 messages. It is useful to set it for static files which should be cached aggressively like images, stylesheets or similar. Options ======= expire.url assigns a expiration to all files below the specified path. The specification of the time is made up of: :: <access|modification> <number> <years|months|days|hours|minutes|seconds> where access means time of user access and modification means time of file modification. Follows following the syntax used by mod_expire in Apache 1.3.x and later. (See: http://httpd.apache.org/docs/1.3/mod/mod_expires.html) Example: :: expire.url = ( "/images/" => "access 1 hours" ) Example to include all sub-directories: :: $HTTP["url"] =~ "^/images/" { expire.url = ( "" => "access 1 hours" ) } Troubleshoot ============ It is known that mod_expire may not work due to an incorrect order of loading of modules. One instance is that mod_expire is loaded after mod_fastcgi. The solution is simple, it is to move mod_expire within the modules array in front of mod_fastcgi. Note: The order of the modules is loaded from top to bottom. Symptoms of the above scenario is the server starts up fine but fails to serve content. }}}
