------解决方案--------------------

这样即可

C# code

string url = "https://data.cathaylife.cn/servlet/HttpDispatcher/KAA0_0100/prompt?newTxRequest=true&syscode=DA&subcode=KAA0";    

HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url);    

myRequest.Method = "GET";

myRequest.Proxy = null;

myRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:11.0) Gecko/20100101 Firefox/11.0";

myRequest.Headers.Add("Accept-Language", "zh-cn,en-us;q=0.8,zh-hk;q=0.6,ja;q=0.4,zh;q=0.2");

myRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";

ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();

MessageBox.Show(new System.IO.StreamReader(myResponse.GetResponseStream(),Encoding.GetEncoding("GB2312")).ReadToEnd());
