Thanks for answer, but still I have doubt.
For security my present config is:
So customers cannot access each other sessions.

Should I direct all clients to one memcache (localhost:11211)? Is it safe?
Or should I run memcache daemons on few ports and each client gets his
own port (client1=localhost:11211, client2=localhost: 11212 etc) ?
