Note Submitter: roberto at spadim dot com dot br ---- instead of memcache, you should consider using redis http://redis.io/commands it have KEYS command (http://redis.io/commands/keys) that can return all keys (like 'ls'/'dir' at php sessions directory) it allow replication too (cluster use) i don't know if anyone wrote a version of phpsessions using redis yet, but since memcache don't have KEYS command, it's hard to know if the users is connected (at app side) or what sessions still active (not expired/not logged)
