I would like to automatically log into a site 'petwholesaler.com' and remain in the site using the HttpWebRequest browser class. I tried the following:


  CookieContainer _siteContainer;
             string _login = "myUserName";
             string _password = "myPassword";
           

             string strPostData = String.Format("username={0}&password={1}", _login, _password);

             // Setup the http request.
             HttpWebRequest wrWebRequest = WebRequest.Create("http://www.petwholesaler.com/login.php?ref=express_order_form") as HttpWebRequest;
             wrWebRequest.Method = "POST";
             wrWebRequest.ContentLength = strPostData.Length;
             wrWebRequest.ContentType = "application/x-www-form-urlencoded";
             _siteContainer = new CookieContainer();
             wrWebRequest.CookieContainer = _yahooContainer;

             // Post to the login form.
             using (StreamWriter swRequestWriter = new StreamWriter(wrWebRequest.GetRequestStream()))
             {
                 swRequestWriter.Write(strPostData);
                 swRequestWriter.Close();
             }

             // Get the response.
             HttpWebResponse response = (HttpWebResponse)wrWebRequest.GetResponse();
              StreamReader myStreamReader = new StreamReader(response.GetResponseStream());
             
             string responseString = myStreamReader.ReadToEnd();
             StreamWriter swrite = new StreamWriter(@"PetWholesaler.html");
              swrite.Write(responseString);
              swrite.Close();

Have a look into bellow code;

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://petwholesaler.com//"); 
            req.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705;)"; 
            req.Method = "POST";
            req.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
            req.Headers.Add("Accept-Language: en-us,en;q=0.5");
            req.Headers.Add("Accept-Encoding: gzip,deflate");
            req.Headers.Add("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7");
            req.KeepAlive = true;
            req.Headers.Add("Keep-Alive: 300");
            req.Referer ="http://petwholesaler.com/login";

            req.ContentType = "application/x-www-form-urlencoded"; 

            String Username = "username";
            String PassWord = "Password";

            StreamWriter sw = new StreamWriter(req.GetRequestStream());
            sw.Write("application=portal&url=http%3A%2F%2Fwww.petwholesaler.com.%2Fportal%2Fredirect%3Bjsessionid%3D1C568AAA1FB8B5C757CF5F68BE6ECE65%3Ftype%3Dssologin%26url%3D%2Fportal%2Fshow%3Bjsessionid%3D1C568AAA1FB8B5C757CF5F68BE6ECE65%3Fidc%3D1023278&realm=sso&userid=" + Username + "&password=" + password + "&x=16&y=11");
            sw.Close();

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


            StreamReader reader = new StreamReader(response.GetResponseStream());
            string tmp = reader.ReadToEnd();

            foreach (Cookie cook in response.Cookies)
            {
                tmp += "\n" + cook.Name + ": " + cook.Value;
            }


            Response.Write(tmp);
            Response.End();
