I need to detect when a session has expired in my Visuial Basic web application. This is what I'm using...

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If CurrentSession.IsNew AndAlso (Not Page.Request.Headers("Cookie") Is Nothing) AndAlso (Page.Request.Headers("Cookie").IndexOf("ASP.NET_SessionId") >= 0) Then
End If something...

End Sub

Note: CurrentSession.IsNew returns HttpContext.Current.Session.IsNewSession

This seems to work well for Internet Explorer, but seems to fail with Firefox.

Can you work with the Session_End function in Global.asax?

I'm only currently using the Application_Error event in the global.asax file. Perhaps my session handling belongs there as well. But, how do I use that on the requested page load?
