failed to get cookie

[Guest]

I'm trying to login to a website with HttpWebRequest. The login page returns
a cookie and a HTTP 302 to redirect to the main page. I only need the cookie
to request the page I really need.

What I did is that:

HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.AllowAutoRedirect = false;

req.CookieContainer = new CookieContainer();
HttpWebResponse resp= (HttpWebResponse)req.GetResponse();

Now I expected the cookie in resp.Cookies, but this is empty
(resp.Cookies.Count == 0).

I sniffed the network traffic so I know exactly what came back from the
server:

HTTP/1.1 302 Moved

The set-cookie header is there! So why is resp.Cookies empty?

When I try with req.AllowAutoRedirect=true the redirect takes me to the main
page BUT also without sending the cookie, so the main page redirects back to
the login page.

Cheers,

Am I the first one to see this problem?

I can work around it when I parse the resp.Headers collection instead of
resp.Cookies. The Set-Cookie header is in resp.Headers, but I would like to
know, how/if this works with resp.Cookies.

Did you ever figure this oen out? I am getting the same problem.

Nope!
I loop through resp.Headers, search for the Set-Cookie header and parse it.
