I think Lennart Regebro already has some nice code to do this bit...
However, it would be nice if this plugin could optionially use a storage
mechanism other than the user's session, in cases where even more
security is required (being able to specify that the cookie should only
be sent by https, hashing with the user's ip address, etc)

The place on the server should also have the same expiration code. ie:
when you expire the cookie, the server side session should also be
removed, so even if someone has stolen a cookie, they can't use it...

I'd prefer to see CookieAuthHelper get better, rather than addign a new
