HttpWebResponse .Cookies

I am writing a simple HTTP Client in .NET. I make an HTTP Request and
examine the response.

I get an empty CookieCollectio n when I do HttpWebResponse .Cookies. However
HttpWebResponse .Headers[Set-Cookie] returns the correct list of cookies
(represented as a comma-separated string) in the response.

Can someone please explain the discrepancy?

Thanks,
Prasanna

If you're making several requests and would like the cookies to be maintained
across all of those requests you should initialize the HttpWebRequest. CookieContainer
for each of those requests with an instance you have around. So like this:

CookieContainer cookies = new CookieContainer ();
HttpWebRequest r = (HttpWebRequest )WebRequest.Cre ate("Page1.aspx ");
r.CookieContain er = cookies;
// do r.GetResponse()
r = (HttpWebRequest )WebRequest.Cre ate("Page2.aspx ");
r.CookieContain er = cookies;

Also, even if you're just doing a single request, it's possible the page
does a redirect and the HttpWebRequest handles this automatically, but unless
you've given it a CookieContainer it will drop cookies across the redirect.

Hi, I place an http request to a web server using HttpWebRequest. When the response comes back (via a HttpWebResponse) the Cookies collection in the response is empty, though if I scan through the response's Headers collection I see that there *are* a number of "Set-Cookie" headers present. Later on in the process I make another request (not to the same Uri though) and the response DOES get its Cookies collection populated correctly.

The second URL times out even if I increase the timeout value significantly. Internet explorer...
