Uri uri = new Uri("http://zhima.cc/member/index_reg.asp");
        System.Net.WebRequest wReq = System.Net.WebRequest.Create(uri);
        System.Net.WebResponse wResp = wReq.GetResponse();
        System.IO.Stream respStream = wResp.GetResponseStream();
        System.IO.StreamReader reader = new System.IO.StreamReader(respStream, System.Text.Encoding.GetEncoding("utf-8"));
        string content = reader.ReadToEnd();
        Response.Write(Server.HtmlEncode( content));
        Response.End();
