I want to redirect the control to Login page whenever the session expires with a message that session has expired. How to do it?

Thank you

Are you using forms authentication? I have found that there's a slight problem when you rely on a session that has value populated from a login. The forms authentication cookie is maintained as long as the browser is open even if the user's session dies. So I put in a check to look at a certain session value. If that value is missing it performs a forms authentication logout to force a return to the login page.

This might help too.

This is code that I have on the login page where I set a Session value if the login is successful and redirect to the default page.

        If Len(Session("EmpID")) = 0 Then
            Response.Redirect("login.asp")
        Else
            Response.Redirect("default.aspx")
        End If

I check for that session value on each page in the application so that if you don't have that session value you get redirected back to the login page.
