Another difference I've found useful:
The HttpSession object can die unexpectedly, especially from a timeout.
Many web servers/servlet engines will time a session out after, say, a
half-hour. Also, the user can quit the browser.
What I did was to create my own UserSession bean. I initialize it with
the HttpSession. The UserSession then registers itself as an
HttpBindingSessionListener. It gets notified when the HttpSession
dies. This lets the UserSession save any data it needs to, and also
close any connections that it may be keeping open.
Cheers,
Tom
