Hi Paul,

There is a way to trap when a session timesout. In your Global.asax file, there is a Session_End event handler that allows you to provide code to run when your application explicitly closes the session or when the session times out.

>>>I guess the one main point behind using tables as opposed to using the session really comes down to this: needing the data to live beyond a session's lifetime in some sort of "raw" (and easily queried) form. Otherwise, the Session and/or Cache a better (performance) bet.
