WebClient website login

Question

I have difficulties logging in to a webpage (http://hurt.prosto.pl); all the time it returns to the login page source... Any idea how to fix it?

var loginData = new NameValueCollection();
loginData.Add("username", username);
loginData.Add("password", password);

var client = new CookieAwareWebClient();
client.BaseAddress = @"http://hurt.prosto.pl/accounts/login/?next=/hurt/";
client.UploadValues("http://hurt.prosto.pl/accounts/login/?next=/hurt/", "POST", loginData);

// now you are logged in and can request pages    
string htmlSource = client.DownloadString("http://hurt.prosto.pl/hurt/myorders/--/category/all1/");
webBrowser2.DocumentText = htmlSource;

This is my CookieAwereWebClient class:

namespace HTMLParser
{
    internal class CookieAwareWebClient : WebClient
    {
        private CookieContainer cookie = new CookieContainer();

        protected override WebRequest GetWebRequest(Uri address)
        {
            WebRequest request = base.GetWebRequest(address);
            if (request is HttpWebRequest)
            {
                (request as HttpWebRequest).CookieContainer = cookie;
            }
            return request;
        }
    }
}

You are logging in twice, no need to do that. Just set the cookie and go to your target page. Also, you do not need to set Content-Type, WebClient does that automatically.
