ASP有函数可以把某个网页通过STREAM下载吗？

       <script language="vbscript">
  Function bytes2BSTR(vIn)
  
  Dim strReturn,i,ThisCharCode,innerCode,Hight8,Low8,NextCharCode
  strReturn = ""
  
  For i = 1 To LenB(vIn)
   ThisCharCode = AscB(MidB(vIn,i,1))
   If ThisCharCode < &H80 Then
   strReturn = strReturn & Chr(ThisCharCode)
   Else
   NextCharCode = AscB(MidB(vIn,i+1,1))
   strReturn = strReturn & Chr(CLng(ThisCharCode) * &H100 + CInt(NextCharCode))
   i = i + 1
   End If
  Next
  
  bytes2BSTR = strReturn
  End Function
  </script>
  <script language="javascript">
  var xmlhttp= new ActiveXObject("Msxml2.xmlhttp")
  xmlhttp.open("GET","http://www.csdn.net/",false)
  xmlhttp.send()
  alert(bytes2BSTR(xmlhttp.ResponseBody))
