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 usefull to set it for static files which should be cached
aggressivly like images, stylesheets or similar.

Options =======

expire.url
assignes 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>

following the syntax used by mod_expire in Apache 1.3.x and later.

Example: ::

expire.url = ( "/images/" => "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.
