c＃CookieContainer没有提取Html / META cookie

Question

我现在正在失去绝对的头脑。我已经完成了大量的HttpWebRequest类型项目，通常不会遇到调试会话无法处理的问题。

我正在使用Fiddler / Chrome网络工具来嗅探网络请求。我正在与Lotus-Domino服务器（.nsf扩展名）进行交互。

该网站有一个初始页面，我也登录了登录凭据。它反过来使用AllowAutoRedirect执行302跟随。这个页面是在Chrome和Fiddler中设置cookie的地方。但是，它没有使用Headers这样做..它在体内使用meta标签，如下所示：

<META HTTP-EQUIV="Set-Cookie"  CONTENT="sh=Y;  path=/; domain=website.com ">

这些cookie不会被响应选中，也永远不会被添加到CookieContainer中。我尝试在重定向后将它们添加到CookieContainer中，但没有运气。以下请求均失败并返回初始登录页面。

var cookieJar = new CookieContainer();

var postData = "username=test&password=letmein";
var url = "https://www.example.com/names.nsf?Login";

var request = (HttpWebRequest)WebRequest.Create(url);
request.KeepAlive = true;
request.Headers["Cache-Control"] = "max-age:0";
request.Headers["Origin"] = "https://www.example.com";
request.Headers["Upgrade-Insecure-Requests"] = "1";
request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36";
request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8";
request.ContentType = "application/x-www-form-urlencoded";
request.Headers["DNT"] = "1";
request.Referer = "https://www.example.com/";
request.Headers["Accept-Encoding"] = "gzip, deflate, br";
request.Headers["Accept-Language"] = "en-US,en;q=0.8";


request.CookieContainer = cookieJar;
request.AllowAutoRedirect = true;
request.MaximumAutomaticRedirections = 20;
request.Method = "POST";

var buffer = Encoding.ASCII.GetBytes(postData);
request.ContentLength = buffer.Length;
var requestStream = request.GetRequestStream();
requestStream.Write(buffer, 0, buffer.Length);
requestStream.Close();

cookieJar.Add(new Uri("http://www.example.com"), new Cookie("sp", "Y", "/", "www.example.com"));
cookieJar.Add(new Uri("http://www.example.com"), new Cookie("coa", "Y", "/", "www.example.com"));
