Ok So i've read that DNN doesn't use the Sessions but it still able to keep the same information that most app store in a session like the user profile. So how does DNN store this kind of information without having to keep querying the database?  Also if I want to utilize the same technique is there an easy way to do that. For example is there a dictionary object available like the Session("key") that I can just store my values?  I know I've read about communicating between modules but there are just some global information that I want to be available to all modules and pages and I want to try and avoid using sessions just to keep everything consistant

thanks
