I just noticed that my code snippet didn't show up due to the script delimiters. For those of you who are interested it was:

If Len(Session("strConn")) = 0 Then
Response.Redirect "timeout.asp"
End If

>Quite true. We use the LEN() function because not only does it tell us if the user's session has timed out, it also serves to prevent users from entering the site in the middle since if they don't use the start page, the connection string doesn't get set.

>>>Because ASP cannot respond to events, Session_OnEnd doesn't really help with this. Testing a Session variable is pretty much your only option. Since we store the ADO connection string to a Session variable, at the top of every page we test it's length using LEN(). If it evaluates to zero, we know the session has timed out and we redirect them to a page that tells them what happened. Our code looks like this:
>>>
>>><%
>>>If Len(Session("strConn")) = 0 Then
>>>Response.Redirect "timeout.asp"
>>>End If
>>>%>

>>>We keep the code in an include file and we've added the include reference into the default ASP page template so it's always there whenever we create a new ASP page.
