如何最好地检测ASP.NET过期的会话？

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

我需要在Visuial Basic Web应用程序中检测会话何时到期。这就是我正在使用的......

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
        Response.Redirect("TimeOut.aspx")
    End If

    ...do something...

End Sub

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

注意：CurrentSession.IsNew返回HttpContext.Current.Session.IsNewSession

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

这似乎适用于Internet Explorer，但似乎与Firefox失败。
