In the main horde_cache cass I dont see that the prefix is used. 
Is only set in the params.

But without the prefix memcache storage is unsable. because memcached server 
is not aware of vhost. Fort the session driver this is not a problem, since 
session ids are unique. But in the normal cache engine, data overlaps, if the 
keys are the same. So the prafix MUST be used in at least in the cache 
implementation.
