ファイルのアップロード後にポップアップ ウィンドウが表示されます。
ClientScript.RegisterStartupScript (Me.GetType(), "Javascript", "javascript:
   window.open ('http://rsspl05/DocAdmin/confirmmsg.aspx?tdnum=" & TDnum &
   "','mywindow','width=800,height=400,location=no');", True)
しかし、私が得るポップアップはページソースのある空白のページです:
<!-- beginning of HttpRedirect.htm file -->
<script type="text/javascript">
function redirectToHttps()     
{     
  var httpURL = window.location.hostname+window.location.pathname;     
  var httpsURL = "https://" + httpURL ;     
  window.location = httpsURL ;     
}     
redirectToHttps();     
</script>
<!-- end of HttpRedirect.htm file -->
実際の aspx コードは次のとおりです。
