I am creating the web service authentication. When the user login with user name and password. Web server will give the token to the client to request the web service with that token. I would like to use the cookie to save the token in order to let the web service to authenticate whether the client's token is correct or not.
The following is my code. please give me example code, if you can.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Text;

namespace AuthWebApplication
    using System.Security.Cryptography;

    /// summary
    /// Summary description for WebService1
    /// /summary
    [WebService(Namespace = "")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    // [System.Web.Script.Services.ScriptService]
    public class WebService1 : System.Web.Services.WebService
        public WebService1()

            //Uncomment the following line if using designed components 
        //public AuthHeader SoapAuthentication;

        [WebMethod(Description = "A sample Web Method to demonstrate a simple web Service Authentication using SOAP Headers")]
        public string SampleWebMethod(string Username, String Password)

            if (Username == "demo" && Password == "123")

                string token = Guid.NewGuid().ToString();

                HttpRuntime.Cache.Add(token, Username, null,





                return token + "is an Authenticated User to access the Web Method";
              //  return Username + " is an Authenticated User to access the Web Method";
                return "Access Denied for " + Username;

You can use Response object to store the content in cookie.
Response.Cookies["userInfo"]["Username"] = "demo";
Response.Cookies["userInfo"]["Password"] = "123";
Response.Cookies["userInfo"].Expires = DateTime.Now.AddDays(1);

string userData ="123";

// Create a cookie authentication ticket.
               ticket = new FormsAuthenticationTicket(
                   1,                                // version
                   Test,                             // user name
                   DateTime.Now,                     // issue time
                   DateTime.Now.AddDays(3),          // expires every hour
                   false,                            // don't persist cookie
                   userData                          // user data
               // Encrypt the ticket
               String cookieStr = FormsAuthentication.Encrypt(ticket);

               // Send the cookie to the client
               HttpContext.Current.Response.Cookies["Testdata"].Value = cookieStr;
               HttpContext.Current.Response.Cookies["Testdata"].Path = "/";
                HttpContext.Current.Response.Cookies["Testdata"].Expires   = DateTime.Now.AddMonths(3);
