One thing to watch out for is the trap of using session data as a dumping ground for global variables. Since you are asking "what belongs in a session", it seems you are already thinking along those lines. I have found that many people who are fond of sessions often use them to store data which I would be personally inclined to store in hidden form data, in a simple cookie, or retrieve from a database when needed. In my systems I usually only store a single "session ID" in a cookie -- a key which references a database row. This allows me to have as much data as I like but keep it all in the database. There is one case where it might make sense to put data into a "session" of some sort -- to cache information which is very time-consuming to retrieve. Minimizing time-consuming database operations is an important thing to think about in large systems, and a place where session data might come in handy.
