Description: | Content cache storage manager keyed to URIs |
---|---|
Status: | Extension |
Module Identifier: | disk_cache_module |
Source File: | mod_disk_cache.c |
mod_disk_cache
implements a disk based storage
manager. It is primarily of use in conjunction with
mod_cache
.
Content is stored in and retrieved from the cache using URI based keys. Content with access protection is not cached.
htcacheclean
can be used to maintain the cache
size at a maximum level.
mod_disk_cache
requires the services of
mod_cache
.
mod_disk_cache
uses the sendfile feature to
serve files from the cache when supported by the platform, and
when enabled with EnableSendfile
.
However, per-directory and .htaccess configuration of
EnableSendfile
are ignored by
mod_disk_cache
as the corresponding settings are not
available to the module when a request is being served from the
cache.
