Question

I have done this code to login,to retrieve and show a webpage :

  // login info array         string postData = 'user_name=tler';         postData += '&user_password=lodvader';         byte[] data = Encoding.ASCII.GetBytes(postData);          // web request         WebRequest req = WebRequest.Create('http://www.lol.com/login.php');         req.Method = 'POST';         req.ContentType = 'application/x-www-form-urlencoded';         req.ContentLength = data.Length;          // stream response to string         Stream newStream = req.GetRequestStream();         newStream.Write(data, 0, data.Length);         newStream.Close();         StreamReader reader = new StreamReader(req.GetResponse().GetResponseStream(), Encoding.GetEncoding('iso-8859-1'));          string responseString = reader.ReadToEnd();          // retrieve text within title         Regex rx = new Regex(@'(?<=<title>).+?(?=</title>)');          var variable = rx.Matches(responseString);          // output         Console.WriteLine(variable[0]);          Console.ReadLine(); 

But, the following page after login is an html redirect like :

<meta http-equiv='refresh' content='3; URL='bb.php'> 

How to follow this link and retrieve next page ?

I have found the time to finish it, here the response ( i tried to be as clear as possible ) :

        // Cookie for our session         var cookieContainer = new CookieContainer();          // Encode post variables         ASCIIEncoding encoding=new ASCIIEncoding();         byte[] loginDataBytes = encoding.GetBytes('user_name=belaz&user_password=123');          // Prepare our login HttpWebRequest         HttpWebRequest request = (HttpWebRequest)WebRequest.Create('http://blabla.fr/verify.php');         request.Method = 'POST';         request.ContentType = 'application/x-www-form-urlencoded';         request.CookieContainer = cookieContainer;         request.ContentLength = loginDataBytes.Length;          // Write encoded post variable to the stream         Stream newStream = request.GetRequestStream();         newStream.Write(loginDataBytes, 0, loginDataBytes.Length);         newStream.Close();          // Retrieve HttpWebResponse         HttpWebResponse response = (HttpWebResponse)request.GetResponse();          // Link the response cookie to the domain         cookieContainer.Add(new Uri('http://blabla.fr/'),response.Cookies);          // Prepare our navigate HttpWebRequest, and set his cookie.         HttpWebRequest requestProfile = (HttpWebRequest)WebRequest.Create('http://blabla.fr/bb.php');         requestProfile.CookieContainer = cookieContainer;          // Retrieve HttpWebResponse         HttpWebResponse responseProfile = (HttpWebResponse)requestProfile.GetResponse();          // Retrieve stream response and read it to end         Stream st = responseProfile.GetResponseStream();         StreamReader sr = new StreamReader(st);         string buffer = sr.ReadToEnd();
