Hi, I have been using RAM-based session management for a while, but never wrote a product for it. Since Graham Chiu has mentioned it again about making a real product, I have taken the time to make one, and called it HappySession. :) Well, in short, it uses cookie for session id, you specify a maximum session expiration time, and expired session data are automatically deleted. It's Zope-transaction-aware. I got a lot of help from Pavlos Christoforou (author of FSSession, a file-system-based session management product.) Thanks a lot, Pavlos! Give it a try. Let me know whether there is any problem. It's easy to use, or at least that's what I have intended. :) It's my very first product, so if there are any bad things that I have done, please let me know.
