asp.net - Redirect to login page after session timeout

Question

I have found some similar questions but none gave me what I really need.

Here is the thing, I have added this to my web.config to handle user session expiration:

<sessionState mode="InProc" timeout="1" />

After 1 minute, the Session_End event from Global.asax is raised:

Sub Session_End(ByVal sender As Object, ByVal e As EventArgs)
    Response.Redirect("Login.aspx")
End Sub

This doesn't work, because:

Response is not available in this context.

(By the way, this question got an anwswer telling that this is ok and it got upvotes).

I don't want nothing fancy. I just want a simple way to redirect the user to the login page when the session time expires. That's all.

Thank you.

Description

You can use the Page_Initevent in the global.asax

Sample

Protected Sub Page_Init(sender As Object, e As EventArgs)
 If Context.Session IsNot Nothing Then
  If Session.IsNewSession Then
   Dim newSessionIdCookie As HttpCookie = Request.Cookies("ASP.NET_SessionId")
   If newSessionIdCookie IsNot Nothing Then
    Dim newSessionIdCookieValue As String = newSessionIdCookie.Value
    If newSessionIdCookieValue <> String.Empty Then
     ' This means Session was timed Out and New Session was started
     Response.Redirect("Login.aspx")
    End If
   End If
  End If
 End If
End Sub
