Syntax: MCacheMaxObjectCount value
Default: MCacheMaxObjectCount 1009
Context: - server config, virtual host
Status: + server config
Status: Experimental
Module: mod_mem_cache
-

The MCacheMaxObjectCount directive sets the maximum - number of objects to be cached. If a new object needs to be inserted in the cache - and the maximum number of objects has been reached, an object will be removed - to allow the new object to be cached. The object to be removed is selected using - the algorithm specified by MCacheRemovalAlgorithm.

Module: mod_mem_cache

The MCacheRemovalAlgorithm directive specifies the algorithm used to select documents for removal from the cache. - Two choices are available:
- LRU (Least Recently Used): LRU removes the - documents that have not been accessed for the longest time.
- GDSF (GreadyDual-Size): GDSF assigns a priority - to cached documents based on the cost of a cache miss and the size of - the document. Documents with the lowest priority are removed first.

Syntax: MCacheSize KBytes
Default: MCacheSize 100
Context: - server config, virtual host
Status: + server config

-

The MCacheSize directive sets the maximum amount of memory - to be used by the cache, in KBytes (1024-byte units). If a new object needs to be - inserted in the cache and the size of the object is greater than the - remaining memory, objects will be removed until the new object can be cached. - The object to be removed is selected using the algorithm specified by - MCacheRemovalAlgorithm.
