Here is a usage example:



 
   

  
    
CookieManager cookieManager = new CookieManager();
// Set a cookie value
cookieManager.CookieValues["FavoriteCookie"] = "Chocolate Chip";

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
// Publish the cookies to the request before asking for the response
cookieManager.PublishCookies(webRequest);

HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();
// Store any cookies returned from the response
cookieManager.StoreCookies(webResponse);

// Get the value of a cookie
string session = cookieManager.CookieValues["SESSIONID"];

webRequest = (HttpWebRequest)WebRequest.Create(url2);
cookieManager.PublishCookies(webRequest);

webResponse = (HttpWebResponse)webRequest.GetResponse();
