使用XMLHTTP制作域名查询系统

<%
On Error Resume Next
Server.ScriptTimeOut=9999999
Function getHTTPPage(Path)
t = GetBody(Path)
getHTTPPage=BytesToBstr(t,"GB2312")
End function

Function GetBody(url)
        on error resume next
        Set Retrieval = CreateObject("Microsoft.XMLHTTP")
        With Retrieval
        .Open "Get", url, False, "", ""
        .Send
        GetBody = .ResponseBody
        End With
        Set Retrieval = Nothing
End Function

Function BytesToBstr(body,Cset)
        dim objstream
        set objstream = Server.CreateObject("adodb.stream")
        objstream.Type = 1
        objstream.Mode =3
        objstream.Open
        objstream.Write body
        objstream.Position = 0
        objstream.Type = 2
        objstream.Charset = Cset
        BytesToBstr = objstream.ReadText
        objstream.Close
        set objstream = nothing

代码我已经在本地测试过了。正常通过。
