HttpListener listener = new HttpListener(); // Add the prefixes. foreach (string s in prefixes) { listener.Prefixes.Add(s); } listener.Start(); Console.WriteLine("Listening..."); // Note: The GetContext method blocks while waiting for a request. HttpListenerContext context = listener.GetContext(); HttpListenerRequest request = context.Request; // This application sends a cookie to the client marking the time // they visited. Cookie timeStampCookie = new Cookie("VisitDate", DateTime.Now.ToString()); // Obtain a response object. HttpListenerResponse response = context.Response; // Add the cookie to the response. response.SetCookie(timeStampCookie); // Construct a response. string responseString = "<HTML><BODY> Hello world!</BODY></HTML>"; response.ContentEncoding = System.Text.Encoding.UTF8; byte[] buffer = System.Text.Encoding.UTF8.GetBytes(responseString); // Send the response. response.Close(buffer, true); listener.Stop(); }
