使用XMLHTTP制作域名查询系统

<%

  getHTTPPage=BytesToBstr(t,"GB2312")
End function

Function GetBody(url)

  Set Retrieval = CreateObject("Microsoft.XMLHTTP")
  With Retrieval

  .Send
  GetBody = .ResponseBody

  objstream.Open
  objstream.Write body

  objstream.Charset = Cset
  BytesToBstr = objstream.ReadText
  objstream.Close
