mod_disk_cache implements a disk based storage
manager. It is primarily of use in conjunction
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.

CacheDirLength directive sets the number
of characters for each subdirectory name in the cache hierarchy.
The result of CacheDirLevels* CacheDirLength
must not be higher than 20.

CacheDirLevels directive sets the number
of subdirectory levels in the cache. Cached data will be saved this
many directory levels below the CacheRoot directory.
The result of CacheDirLevels*
CacheDirLength must
not be higher than 20.

| 模塊 | mod_disk_cache |
CacheRoot directive defines the name of
the directory on the disk to contain cache files. If the mod_disk_cache module has been loaded or compiled in to the
Apache server, this directive must be defined. Failing to
provide a value for CacheRoot will result in
a configuration file processing error. The CacheDirLevels和CacheDirLength directives define
the structure of the directories under the specified root directory.
CacheRoot c:/cacheroot
