How do I call javascript just before a response redirect

I'm trying to run some java script just before a page redirect but it fails to run.
When I comment out the Response.Redirect all works fine but this goes against the particular requirements. Any ideas on how to implement this functionality?

        Dim strscript As String = <script>alert('hello');</script>



        If Not ClientScript.IsClientScriptBlockRegistered(clientscript) Then

            ClientScript.RegisterStartupScript(Me.GetType(), clientscript, strscript)

        End If



        Response.Redirect(http://www.google.com)

Your problem is that the Response.Redirect redirects the response (...) before anything is sent back to the client. So what the client gets is a response from Google rather than from your server.

In order to write some javascript on the page and have it execute before sending the client to Google, you'll need to do your redirect in javascript after the alert.

   Dim strscript As String = <script>alert('hello');window.location.href='http://www.google.com'</script>



   If Not ClientScript.IsClientScriptBlockRegistered(clientscript) Then

       ClientScript.RegisterStartupScript(Me.GetType(), clientscript, strscript)

   End If
