WebForms Idle timeout how to redirect to page (Windows Auth)

Question

Hi,

 I am working on  old application.

ASp.NET with VB.NET web forms.

It has windows authentication  so when idel timeout happens it comes to Session_end event.

Sub Session_End(ByVal sender As Object, ByVal e As EventArgs)
' Fires when the session ends

End Sub

This is fine but, need to redirect user to a different page.

 

Response.Redirect and Server.Transfer doesn't work here.

 

Please let me know any sugegstions. 

 

Thanks,

 Tushar
