I'm using Zend Framework.
I want to do something similar to SO, when you are not a registered user, you keep your account as long as you remove all your cookies.
I know that session <> cookies, however what will be the best way to do that?
By the way, I'm using memcached because I plan to share sessions between frontend.
Is there any recommendations about this? because memcached data are volatile.
May I need to store them in a database instead?
