As already stated by Mike, there's quite a bit of geo related
intermediary glue code that translates the incoming request into the
actual name of the tile as stored on the system, which makes the
module much more specific than the mod_*_cache existing modules.
There is a memcached storage backend for mapcache, but speed of access
to the tile data is not a use-case that it shines at: it is slower
than disk based caches, but allows the automatic expiring of tiles
based on their creation date.

c.f. the fastcgi implementation. cgi is not a recommended setup.
