Description:

This module requires the service of mod_cache. It acts as a
support module for mod_cache and provides a 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).

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