Redirect to another asp page after file download

I have a page that has the below code
Dim strAccountTypeID
Select Case Request.QueryString("Func")
      Case "GetFormsData"
        If (( Request.QueryString("source") = "opennewacct" ) And ( Request.QueryString("SelectedAccNumber") <> 0 )) Then
            XMLString=GetFormsData(Request.QueryString("SelectedForms"),Request.QueryString("SelectedAccNumber"),Request.QueryString("SelectedAccType"),Request.QueryString("SelectedAdvisor"))
            Set xml_doc = CreateObject("Microsoft.XMLDOM")
            xml_doc.async = False
            xml_doc.loadXML(XMLString)
       
            Set Root = xml_doc.documentElement
            Set NodeList = Root.getElementsByTagName("ClientNumber")
     
            For Each Elem In NodeList
                Set Text = Elem.firstChild
                Text.replaceData 0, 9, ""
                Response.ContentType = "application/x-~ls"
                Response.write xml_doc.XML
            Next
        ElseIf (Request.QueryString("SelectedAccType") = "GetAccountType") Then
            strAccountTypeID = GetAccountTypeID(Request.QueryString("SelectedForms"),Request.QueryString("SelectedAccNumber"))
            Response.ContentType = "application/x-~ls"                        
            Response.Write GetFormsData(Request.QueryString("SelectedForms"),Request.QueryString("SelectedAccNumber"),strAccountTypeID,Request.QueryString("SelectedAdvisor"))  
        Else
            Response.ContentType = "application/x-~ls"
            Response.Write GetFormsData(Request.QueryString("SelectedForms"),Request.QueryString("SelectedAccNumber"),Request.QueryString("SelectedAccType"),Request.QueryString("SelectedAdvisor"))  
        End If
    Case "GetFormGUID"
            Response.Write (GetFormGUID(Request.QueryString("SelectedForms")))
      Case Else
            Response.Write ""
End Select
Response.Flush()
