Comment	>>> The default value for memcache caching prefix >>> ($conf['cache']['params']['prefix']) is empty, so a duplicate prefix >>> would be an issue with your local installation. >> >> 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 > > I still don't understand why this is an issue.
