C＃HttpWebRequest Cookie未传输

Question

I'm trying to transmit two manually created Cookies with a initial request from the client to a server (no response available, where the Cookies could be extracted) using the following code (as discussed eg here )

HttpWebRequest request = 
      (HttpWebRequest)HttpWebRequest.Create(
      "https://intra.group.net:5115/app/search.do");

//...

CookieContainer oCookies = new CookieContainer();
CookieCollection cookieGroup = new CookieCollection();
Cookie c1 = new Cookie("name1", "value1", "/", ".intra.group.net");
Cookie c2 = new Cookie("name2", "value2", "/", ".intra.group.net");
cookieGroup.Add(c1);
cookieGroup.Add(c2);
oCookies.Add(cookieGroup);
request.CookieContainer = oCookies;

But raw communication doesn't contain (according to Fiddler) any Cookie data. Any suggestions why they are missing? Thank you very much in advance!

Answer 1

Maybe it's some synchronize problem. Sometimes the problem is the HttpOnly cookies that are missing from Document.Cookie for security reasons.You can try this solution here .

Answer 2

Cookies are received in the HttpWebRequest, not sent.

They are Sent with the WebReponse.

-> HttpContext.Current.Request : Contains Received Cookies

-> HttpContext.Current.Response: Contains cookies sent back to browser.

Add your cookies to the response instead of the request.

HttpCookie cookie = HttpContext.Current.Response.Cookies["someCookie"]
if (cookie != null)
  HttpContext.Current.Response.Cookies.Remove(cookie);

HttpCookie updatedCookier = new HttpCookie....
HttpContext.Current.Response.Cookies.Add(updatedCookie);

I am not sure if this will work for you but a few months back i was doing something similar where i manually paste cookies in the HttpWebrequest and it worked so try this:

Assuming postReq= WebRequest.

HttpWebRequest request =(HttpWebRequest)HttpWebRequest.Create("SomeUrl");
postReq.Headers.Add("Cookie: PREF=ID=17337a16083851b1:");// You can get this from fiddler

Post it all in one line....
