I’m doing some experimenting with HttpWebRequest, and need to get it working with SSL. It does work on some websites (PayPal, for instance), but not the ones I actually want it working on, such as this community website (URL is also in the code sample). Why is this? The certificates (I’m assuming this is where the problem might be) look awful similiar.

    public static bool AcceptAllCertificatePolicy(object sender,
                                            X509Certificate certificate,
                                            X509Chain chain,
                                            SslPolicyErrors sslPolicyErrors)
    {
        return true;
    }

    static void LoginTest()
    {

        ServicePointManager.ServerCertificateValidationCallback += AcceptAllCertificatePolicy;

        HttpWebRequest req = (HttpWebRequest)
        WebRequest.Create("https://steamcommunity.com");

        req.Method = "GET";

        req.CookieContainer = new CookieContainer();

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

        Console.WriteLine("Cookies:" + resp.Cookies.Count + "\r\n" + resp.ResponseUri);
        Console.WriteLine(resp.Headers);

        resp.Close();
    }

Thanks

EDIT: The URL was incorrect, sorry. Problem persists though.

EDIT2:
I forgot to mention that while it doesn’t give me any errors, it doesn’t return any cookies either. That’s what I’m really after.
http://www.paypal.com gives me 7 cookies, response headers being

    Install firebug for firefox. Clear your cookie cache, and then navigate to the site. Check in firebug to see what is the exact request sent by the browser. Then replicate the exact same request using code. This means replicating all headers sent by the browser.

    Some servers will not send cookies if they dont think that it is a browser issuing the request. So, putting all the request headers should make it appear to the site as if a browser is requesting the pages.
