mod_cache implements an RFC 2616 compliant HTTP content cache that
can be used to cache either local or proxied content. mod_cache
requires the services of one or more storage management modules.
Two storage management modules are included in the base Apache
* mod_disk_cache - implements a disk based storage manager for
use with mod_proxy.
* mod_mem_cache - implements an in-memory based storage manager.
mod_mem_cache can be configured to operate in two modes: caching
open file descriptors or caching objects in heap storage.
mod_mem_cache is most useful when used to cache locally generated
content or to cache backend server content for mod_proxy
configured for ProxyPass (aka reverse proxy)
