Module: mod_expire
Description¶

- Content Caching
- Description
- Options
mod_expire controls the Cache-Control: max-age response header in HTTP/1.1 or later, and Expires response header in HTTP/1.0. These caching headers are useful to set for static files which should be cached aggressively like images, javascript, stylesheets, or similar.
Options¶
expire.url
assigns a expiration to all files below the specified path prefix. The specification of the time is made up of:<access|modification> plus <number> <years|months|days|hours|minutes|seconds>
where access means time of user access and modification means time of file modification.
This follows the syntax used by Apache mod_expire. (https://httpd.apache.org/docs/current/mod/mod_expires.html)
Example: expire.url = ( "/images/" => "access plus 1 hours" )
Example to include all sub-directories:
$HTTP["url"] =~ "^/images/" { expire.url = ( "" => "access plus 1 hours" ) }
expire.mimetypes (since 1.4.43)
assigns a expiration to all responses with Content-Type prefix matching the listed mimetypes (prefix match).
The syntax is the same as expire.url
, except using mimetypes instead of urls.
Example: expire.mimetypes = ( "text/" => "access plus 1 hours" )
