CookieContainer Property

HttpWebRequest.CookieContainer Property


Gets or sets the cookies associated with the request.

Namespace:   System.Net
Assembly:  System (in System.dll)

public virtual CookieContainer CookieContainer { get; set; }

Property Value

Type: System.Net.CookieContainer

A CookieContainer that contains the cookies associated with this request.

The CookieContainer property provides an instance of the CookieContainer class that contains the cookies associated with this request.

CookieContainer is null by default. You must assign a CookieContainer object to the property to have cookies returned in the Cookies property of the HttpWebResponse returned by the GetResponse method.


For security reasons, cookies are disabled by default. If you want to use cookies, use the CookieContainer property to enable cookies.

The following code example sends a request to a URL and displays the cookies returned in the response.

using System.Net;
using System;
namespace Examples.System.Net.Cookies
    // This example is run at the command line.
    // Specify one argument: the name of the host to 
    // send the request to.
    // If the request is sucessful, the example displays the contents of the cookies
    // returned by the host.

    public class CookieExample
        public static void Main(string[] args)
            if (args == null || args.Length != 1)
                Console.WriteLine("Specify the URL to receive the request.");
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(args[0]);
            request.CookieContainer = new CookieContainer();

            HttpWebResponse response = (HttpWebResponse) request.GetResponse();

            // Print the properties of each cookie.
            foreach (Cookie cook in response.Cookies)
                Console.WriteLine("{0} = {1}", cook.Name, cook.Value);
                Console.WriteLine("Domain: {0}", cook.Domain);
                Console.WriteLine("Path: {0}", cook.Path);
                Console.WriteLine("Port: {0}", cook.Port);
                Console.WriteLine("Secure: {0}", cook.Secure);

                Console.WriteLine("When issued: {0}", cook.TimeStamp);
                Console.WriteLine("Expires: {0} (expired? {1})", 
                    cook.Expires, cook.Expired);
                Console.WriteLine("Don't save: {0}", cook.Discard);    
                Console.WriteLine("Comment: {0}", cook.Comment);
                Console.WriteLine("Uri for comments: {0}", cook.CommentUri);
                Console.WriteLine("Version: RFC {0}" , cook.Version == 1 ? "2109" : "2965");

                // Show the string representation of the cookie.
                Console.WriteLine ("String: {0}", cook.ToString());

// Output from this example will be vary depending on the host name specified,
// but will be similar to the following.
