FormsAuthentication的过期问题

你可以弄个 session如果FormsAuthentication.SetAuthCookie设置登录成功就给session赋值，你打开浏览器的时候判断这个session是否为null，如果为null就设置FormsAuthentication.SetAuthCookie过期

或者不要给System.Web.Security.FormsAuthenticationTicket设置过期时间
不要给System.Web.Security.FormsAuthenticationTicket设置过期时间
protected void btnLogin_Click(object sender, EventArgs e)
        {
                var ticket = new System.Web.Security.FormsAuthenticationTicket(1, this.txtName.Text, DateTime.Now, DateTime.Now.AddDays(1), false, "USER");
                var encryptedTicket = System.Web.Security.FormsAuthentication.Encrypt(ticket);                if (Request.Cookies[System.Web.Security.FormsAuthentication.FormsCookieName] != null)
                    Request.Cookies.Remove(System.Web.Security.FormsAuthentication.FormsCookieName);                var loginIdentify = new HttpCookie(System.Web.Security.FormsAuthentication.FormsCookieName);
              //  loginIdentify.Expires = DateTime.Now.AddDays(1);
                loginIdentify.Value = encryptedTicket;                Response.AppendCookie(loginIdentify);
                if (!String.IsNullOrEmpty(Request.QueryString["ReturnUrl"]) && !Request.QueryString["ReturnUrl"].ToLower().Contains("profile"))
                    Response.Redirect(Server.UrlDecode(Request.QueryString["ReturnUrl"]));
                else
                    Response.Redirect(System.Web.Security.FormsAuthentication.DefaultUrl);
        }loginIdentify.Expires = DateTime.Now.AddDays(1);注释掉就关闭浏览器就过期了，自己用这个代码试试
