avoiding DB interaction is a good thing, and session storage is your friend
as for cookies, you cannot trust them (e.g. despite I posted the maximum
allowed 100 msgs I can send a cookie saying I'm "firstpost" and keep spamming)
I guess if a user profile is not too big, you should have it available in
session.
