write to response stream *after* response.redirect? (redirect PLUS modal dialog)

Hello-

I'm trying to redirect a response AND popup a dialog explaining why.

Here's the code I've been using to popup messages, but I am not having any luck putting it before or after the Response.Redirect:

  System.Web.HttpContext.Current.Response.Write("<SCRIPT LANGUAGE=""JavaScript"">" & vbCrLf)
  System.Web.HttpContext.Current.Response.Write("alert(""" & MessageHere & """)" & vbCrLf)
  System.Web.HttpContext.Current.Response.Write("</SCRIPT>")

Any help greatly appreciated-

VB.NET 1.1

Response.Redirect is performed on the server thus you must decide if you want to display message before last postback on original page or on load event in new page. You can do e.g. this:

Original page:
       Session("redirecting") = True
       Response.Redirect("default4.aspx")

New page:
       If not Page.IsPostBack Then
         If Session("redirecting") = True then
            System.Web.HttpContext.Current.Response.Write("<SCRIPT LANGUAGE=""JavaScript"">" & vbCrLf)
            System.Web.HttpContext.Current.Response.Write("alert(""" & MessageHere & """)" & vbCrLf)
            System.Web.HttpContext.Current.Response.Write("<")
            System.Web.HttpContext.Current.Response.Write("/")
            System.Web.HttpContext.Current.Response.Write("SCRIPT>")
         End If
        End If

Another solution. Insead of response.redirect on original page use this code:

            Dim scriptString As String = "<script language=JavaScript>alert('message'); window.location='secondpage.aspx';"
            scriptString += "<"
            scriptString += "/"
            scriptString += "script>"
            If (Not IsClientScriptBlockRegistered("clientScript")) Then
                RegisterClientScriptBlock("clientScript", scriptString)
            End If

Thanks the_paab!  

I just put the message string in the session, check for it on load, then display it and set it back to nothing.
