I have setted $conf['cache']['params']['prefix'] because i have  
multiple horde instances (vhosts) in the same memcache...
If the value of $conf['cache']['params']['prefix'] is something like  
'ABC' then i will have on my memcache duplicate keys like:
ABC_horde_perms_sql
ABC_ABC_horde_perms_sql
and for some others i even have triplicates!!!
ABC_ABC_ABC_horde_perms_sql

Picking up a practical example:
Horde_Cache_Storage_Memcache method set(), adds the prefix to the key  
and then calls $this->_memcache->set().. and this method will also  
append the prefix to the $key, thus making it duplicate
