HttpWebResponse and Cookies

[Tom Jones]

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.

Anyone have any idea what might be going on here?

Thanks,
tj

Can you provide some sample code or the site's URL where you don't get
cookies?

Can you post the Set-Cookie contents and the URL where the original request
is being made. The reason may be obvious once you look at the cookies
themselves. (Not every cookie should be sent back).

Hi Nick,

[I also work at MS btw... ;-), Whidbey]

It looks like the main issue was that I was not allocating a new instance of
the CookieContainer and associating it with the *request*. As soon as I did
that, my responses had the expected cookie objects.

How do I determine if a cookie should be sent back or not?

Thanks,

Hello TJ,

Alas, if a cookie is in the container... send it back.
Cookies that don't go back are cookies that arrive expired. I've heard of
some interesting uses of expired cookies, especially from spyware.
