mod_disk_cache Content cache storage manager keyed to URIs Experimental mod_disk_cache.c disk_cache_module This module is experimental. Documentation is still under development...

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

Content is stored in and retrieved from the cache using URI based keys. Content with access protection is not cached.

Note:

mod_disk_cache requires the services of mod_cache.

 CacheRoot The directory root under which cache files are stored CacheRoot directory server configvirtual host

The 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 and CacheDirLength directives define the structure of the directories under the specified root directory.

CacheRoot c:/cacheroot CacheDirLevels The number of levels of subdirectories in the cache. CacheDirLevels levels CacheDirLevels 3 server configvirtual host

The 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.

 CacheDirLevels 5 CacheDirLength The number of characters in subdirectory names CacheDirLength length CacheDirLength 2 server configvirtual host

The 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.

 CacheDirLength 4 CacheMinFileSize The minimum size (in bytes) of a document to be placed in the cache CacheMinFileSize bytes CacheMinFileSize 1 server configvirtual host

The CacheMinFileSize directive sets the minimum size, in bytes, for a document to be considered for storage in the cache.

CacheMinFileSize 64 CacheMaxFileSize The maximum size (in bytes) of a document to be placed in the cache CacheMaxFileSize bytes CacheMaxFileSize 1000000 server configvirtual host

The CacheMaxFileSize directive sets the maximum size, in bytes, for a document to be considered for storage in the cache.

CacheMaxFileSize 64000
