!急，httpWebRequest如何获取跨域Cookie

Question

问题是这样的：
httpWebRequest获取一个地址如：www.xx.com,同时设置了一个ref CookieContainer供设置和接收Cookie，
正常网页请求时服务器会设置xx.com域下的Cookie，httpWebRequest里的Cookie没法获取xx.com域下的Cookie。
需要如何设置，求高手帮帮忙。

Answer 1

跟帖，我也想知道，怎么样模拟别人的cookie

Answer 2

CookieContainer.GetCookies 
CookieContainer cookieContainer = new CookieContainer();
req.CookieContainer = cookieContainer

Answer 3

HttpWebRequest request = null;
                HttpWebResponse response = null;
                request = (HttpWebRequest)HttpWebRequest.Create(url);
                request.Headers = header;
                request.AllowWriteStreamBuffering = false;
                request.CookieContainer = cc;
                request.Accept = "*/*";
                request.Headers.Add("p3p", "CP=CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR");
                request.UserAgent = userAgent;
                request.KeepAlive = true;
                request.AllowAutoRedirect = true;
                request.ContentLength = postData.Length;
                request.ContentType = "application/x-www-form-urlencoded";                if (!string.IsNullOrEmpty(refUrl))
                {
                    request.Referer = refUrl;
                }
                if (isPost)
                {
                    request.Method = "POST";
                    byte[] finalPostData = encoding.GetBytes(postData);
                    Stream newStream = request.GetRequestStream();
                    newStream.Write(finalPostData, 0, finalPostData.Length);
                    newStream.Close();
                }
                else
                {
                    request.Method = "GET";
                }
                response = (HttpWebResponse)request.GetResponse();
                foreach (Cookie cookie in response.Cookies)
                {
                    cc.Add(cookie);
                }
//按理说这里应该可以获得其它域下的Cookie，但是我得到的只有当前请求域下的Cookie，顶级域下的没法获得，还有我设置了P3P head也得不到
                return response.GetResponseStream();

Answer 4

说下解决方案：
使用socket发起http请求，自行解析header分析cookie补充一下：httpwebrequest在很多场合都满足不了需求，socket才是王道。

Answer 5

那就是说 你的的确确 是可以获取 到 别人网站的cookie吗？
