Answer 1

HttpWebRequest req = (HttpWebRequest)WebRequest.Create(new Uri(url));
                    req.UserAgent = reqUserAgent;
                    req.CookieContainer = _cc;
                    req.Referer = referer;
                    byte[] buff = Encoding.GetEncoding("GB2312").GetBytes(content);
                    req.Method = "POST";
                    req.Timeout = _timeout;
                    req.ContentType = "application/x-www-form-urlencoded";
                    req.ContentLength = buff.Length;
                    if (null != _proxy && null != _proxy.Credentials)
                    {
                        req.UseDefaultCredentials = true;
                    }
                    req.Proxy = _proxy;
                    //req.Connection = "Keep-Alive";
                    Stream reqStream = req.GetRequestStream();
                    reqStream.Write(buff, 0, buff.Length);
                    reqStream.Close();                    //接收返回字串
                    HttpWebResponse res = (HttpWebResponse)req.GetResponse();
                    StreamReader sr = new StreamReader(res.GetResponseStream(), Encoding.Default);
                    return sr.ReadToEnd();
我是用这样的http方式访问外部的websevice，该怎么处理？

Answer 2

上传还可以实现,大不了读的慢点
GetResponse的时候可就由不得客户端了建议在网络设备上实现

Answer 3

把连接超时设置到1S以上。  
做计数器，记录每秒下载的字节数。  
在下载线程中判断“当前秒”中下载的字节数是否超限。超限了就停止下载。  
等到下一秒再开始新的下载。 Thread.Sleep(sleep);延迟
