【懂Cookies保持的老鸟请进】——话说HttpWebRequest，HttpWebResponse中怎样梅开二度，再续前缘。
在WinFrom的HttpWebRequest或Respone中，

可以利用：        CookieContainer 来保存Cookie，让后续的页面继续使用保存下来的Cookie，如：

  /// <summary>

        /// 解析Cookie

        /// </summary>

        /// <param name="response"></param>

        private void ParseCookie(HttpWebResponse response)

        {

            if (!IgnoreCookies)

            {

                string cookiesExpression = response.Headers["Set-Cookie"];

                if (!string.IsNullOrEmpty(cookiesExpression))

                {

                    Uri cookieUrl = new Uri(string.Format("{0}://{1}:{2}/",

                        response.ResponseUri.Scheme,

                        response.ResponseUri.Host,

                        response.ResponseUri.Port));



                    _cookieContainer.SetCookies(cookieUrl, cookiesExpression);

                }

            }

        }

当访问其他页面时，只要再调用 

 /// <summary>

        /// 配置请求设置

        /// </summary>

        /// <param name="request"></param>

        private void ConfigRequest(HttpWebRequest request)

        {

            request.UserAgent = UserAgent;

            request.Referer= "";            

            request.CookieContainer = _cookieContainer;

            request.AllowAutoRedirect =AllowAutoRedirect;

            request.MediaType = "text/html";

            request.Headers["Accept-Language"] = "zh-CN,zh;q=0.8";

            if (Timeout >&nb
