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](https://steamcommunity.com "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.
www.paypal.com gives me 7 cookies, response headers being
