HttpWebResponse not get cookies? It turned out to be a jump.

Today, when doing a mock landing, found that HttpWebResponse's cookies are empty, but fiddler see there is ... Later see is 302 State, just know request this time, response back already is jump ... This will cause the cookie to disappear.

Workaround:

1.

var request = (HttpWebRequest) webrequest.create (URL));

Request. Cookiecontainer = new Cookiecontainer (); We all know that if you want to get response's cookie, this must be written.
request. AllowAutoRedirect = false;

2. If you are using WebClient, you need to rewrite this class:

public class Webclientex:webclient    {        protected override WebRequest GetWebRequest (Uri address)        {            var Request = (HttpWebRequest) base. GetWebRequest (address);           request. AllowAutoRedirect = false;            return request;        }    }

var webClient = new Webclientex ();
