You can't do a redirect .. or any client output... in onsessionend() ...
because that runs when the session is over.
Maybe something like this:
<cffunction name="onrequeststart" blah blah....
<cfif not IsDefined("session.whatever")>
<cflocation url="/login...">
</cfif>
What I do in that instance is check their cookie. I keep my session lengths
short to preserve memory, but if they have a valid cookie that hasn't
expired, i start the session again right there... by the time the form
submits in the onrequest method, they have a valid session again. That may
not meet security requirements for some applications however.
