    static CookieContainer MyCookieContainer = new CookieContainer();    // global static - so that it can remember all cookies

    wRequest.CookieContainer = MyCookieContainer;

 

    WebResponse wResponse = wRequest.GetResponse();

    System.IO.StreamReader sReader = new System.IO.StreamReader(rStream);
