能实现这个功能吗？
在客户打开我网页的同时，可否让客户端向第三方站点“ＧＥＴ”或“ＰＯＳＴ”数据？
没学过asp.net，不知道用 "HttpWebRequest "行不行？

行
HttpWebRequest myReq = (HttpWebRequest)HttpWebRequest.Create(a_strUrl);
myReq.Timeout = timeout;
HttpWebResponse HttpWResp = (HttpWebResponse)myReq.GetResponse();
Stream myStream = HttpWResp.GetResponseStream();
StreamReader sr = new StreamReader(myStream, Encoding.Default);
StringBuilder strBuilder = new StringBuilder();
