C# Website Login & webbrowser1 navigate problem // EASY

Hello, I have an app which has 1 webbrowser, 1 richtextbox, 1 button. I am using this code: CookieCollection cookies = new CookieCollection(); HttpWebRequest request = (HttpWebRequest)[login to view URL]("[login to view URL]"); [login to view URL] = new CookieContainer(); [login to view URL](cookies); //Get the response from the server and save the cookies from the first request.. HttpWebResponse response = (HttpWebResponse)[login to view URL](); cookies = [login to view URL]; string getUrl = "[login to view URL]"; string postData = [login to view URL]("login={0}&password={1}&op=login", "XXXX", "XXXX"); HttpWebRequest getRequest = (HttpWebRequest)[login to view URL](getUrl); [login to view URL] = new CookieContainer(); [login to view URL](cookies); //recover cookies First request [login to view URL] = [login to view URL]; [login to view URL] = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/[login to view URL] Safari/535.2"; [login to view URL] = true; [login to view URL] = [login to view URL]; [login to view URL] = true; [login to view URL] = "application/x-www-form-urlencoded"; byte[] byteArray = [login to view URL](postData); [login to view URL] = [login to view URL]; Stream newStream = [login to view URL](); //open connection [login to view URL](byteArray, 0, [login to view URL]); // Send the data. [login to view URL](); HttpWebResponse getResponse = (HttpWebResponse)[login to view URL](); using (StreamReader sr = new StreamReader([login to view URL]())) { string sourceCode = [login to view URL](); [login to view URL] = sourceCode; } [login to view URL]("[login to view URL]"); But the webbrowser1 doesn't navigate to [login to view URL] , because its asking the user / pass again, however in the richtextbox i can see that i am logged in.. maybe navigate must use a cookie as well? thanks
