处理方法
[HttpPost]
        public ActionResult Index(Models.User model) {
            if (model.UserName == "admin")
            {
                //创造票据
                FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(model.UserName, false, 1);
                //加密票据
                string ticString = FormsAuthentication.Encrypt(ticket);
                //输出到客户端
                Response.Cookies.Add(new HttpCookie(FormsAuthentication.FormsCookieName, ticString));
                //跳转到登录前页面
                return Redirect(HttpUtility.UrlDecode( Request.QueryString["ReturnUrl"]));
            }
            return View();
        }

退出.

通过 new FormsAuthenticationTicket(model.UserName, false, 时长); 设置.AXPXAUTH过期时长. 但是如果newHttpCookie(FormsAuthentication.FormsCookieName, ticString) 这个cookie对象没有设置过期时间, 那么上面设置的时长再长, cookie的生命周期还是浏览器的生命周期.

public ActionResult Logout() {
            FormsAuthentication.SignOut();
            return Redirect(FormsAuthentication.LoginUrl);
        }
