This module allows your Apache 2.2.x installation to serve cached data quickly from one or more memcached server instances rather than from your file system. Like other caching modules available (mod_file_cache, mod_disk_cache, mod_mem_cache, etc.) this module lets you configure some basic parameters in your httpd.conf to enable caching based on specific criteria. Unlike the others, mod_memcache_cache allows cached data to be shared across multiple Apache instances.

Note that this module is different that the Apache distributions mod_mem_cache, which cache's data in the running httpd process memory.
