It is basically a function that looks in the session for a value referenced by a constant called CartSessionKey. If it doesn't exist it checks to see if there is a current user - if there is it users their name as the cart key, otherwise it generates a new Guid. Finally it returns the Cart Key value to the called.

The HttpContextBase part is just a means of passing the current HttpContext to a method that isn't in a page.
