Summary
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.
Note:
mod_disk_cache requires the services of
mod_cache.
Note:
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.

the structure of the directories under the specified root directory.
