mod_disk_cache Content cache 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 for use with mod_proxy.

Content stored and retrived keyed to the URL. Content with access protections is not cached.

mod_disk_cache requires the services of mod_cache.

 CacheRoot The directory to store cache files CacheRoot directory none server config

The CacheRoot directive defines the name of the directory on the disk to contain cache files. What is happening if not set ?

CacheRoot c:/cacheroot
CacheSize The maximum amount of disk space that will be used by the cache in KBytes CacheSize KBytes CacheSize 1000000 server config

The MCacheSize directive sets the desired disk space usage of the cache, in KBytes (1024-byte units). This directive does not put a hard limit on the size of the cache. The garbage collector will delete files until the usage is at or below the settings. Always use a value that is lower than the available disk space.

MCacheSize 5000000
CacheGcInterval The interval between garbage collections CacheGcInterval hours server config CacheGcInterval 24
The CacheGcInterval directive is currently not implemented. CacheDirLevels The number of levels of subdirectories in the cache CacheDirLevels levels CacheDirLevels 3 server config

The CacheDirLevels directive sets the number of subdirectory levels in the cache. Cached data will be saved this many directory levels below CacheRoot

CacheDirLevels*CacheDirLength value must not be higher than 20.

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

The CacheDirLength directive sets the number of characters for each subdirectory in the cache

CacheDirLevels*CacheDirLength value must not be higher than 20.

 CacheDirLength 4
CacheExpiryCheck On if cache observes Expires date when seeking files CacheExpiryCheck binary CacheExpiryCheck ? server config CacheExpiryCheck On
 The CacheExpiryCheck directive is currently not implemented. CacheMinFileSize The minimum size (in bytes) of a file to be placed in the cache CacheMinFileSize bytes CacheMinFileSize 1 server config

The CacheMinFileSize directive sets the minimum size in bytes of a file to be cached.

CacheMinFileSize 64
 CacheMaxFileSize The maximum size (in bytes) of a file to be placed in the cache CacheMaxFileSize bytes CacheMaxFileSize 1000000 server config

The CacheMaxFileSize directive sets the maximum size in bytes of a file to be cached.

CacheMaxFileSize 64000
 CacheTimeMargin The minimum time margin to cache a document CacheTimeMargin ? CacheTimeMargin ? server config CacheTimeMargin
 CacheGcDaily The time of day for garbage collection (24 hour clock) CacheGcDaily time CacheGcDaily ? server config CacheGcDaily
 The CacheGcDaily directive is currently not implemented. CacheGcUnused The time in hours to retain unused file that match a url CacheGcUnused hours CacheGcUnused ? server config CacheGcUnused
 The CacheGcUnused directive is currently not implemented. CacheGcClean The time in hours to retain unchanged files that match a url CacheGcClean hours CacheGcClean ? server config CacheGcClean
 The CacheGcClean directive is currently not implemented. CacheGcMemUsage The maximum kilobytes of memory used for garbage collection CacheGcMemUsage KBytes CacheGcMemUsage ? server config CacheGcMemUsage
 The CacheGcMemUsage directive is currently not implemented.
