0594 Cookies

A cookie is a name/value string pair that an HTTP server sends to a client in a response header. A web browser client typically remembers cookies, and replays them to the server in each subsequent request until their expiry. A cookie allows a server to know whether it's talking to the same client. By default, HttpWebRequest ignores any cookies received from the server. To accept cookies, create a CookieContainer object and assign it to the WebRequest. The cookies received in a response can then be enumerated. using System; using System.Net; using System.Threading; using System.IO; using System.Text; class ThreadTest { static void Main() { var cc = new CookieContainer(); var request = (HttpWebRequest)WebRequest.Create("http://www.google.com"); request.Proxy = null; request.CookieContainer = cc; using (var response = (HttpWebResponse)request.GetResponse()) { foreach (Cookie c in response.Cookies) { Console.WriteLine(" Name: " + c.Name); Console.WriteLine(" Value: " + c.Value); Console.WriteLine(" Path: " + c.Path); Console.WriteLine(" Domain: " + c.Domain); } } } } The output: Name: PREF Value: ID=cb381517b8a3f042:FF=0:TM=1292697686:LM=1292697686:S=2ChHqoVy2ucH4Mcv Path: / Domain: .google.ca Name: NID Value: 42=GAwfQ-bE0QZ_7oesm0ZW-jBXs-D4Y17W9jLhp3BUkGraIdKis5o5mmJxwjL0orccq8XZOTHi2ZMO6nxgI7dWyDXv4p-e5ZQ1hj8kJpQTD95xZodUSU5jsvhr0_ssbKkm Path: / Domain: .google.ca
