本文介绍了一种通过检查请求中的用户令牌是否存在来批量删除网站所有Cookie的方法，确保了网站的用户认证状态不会被意外保留。

    private static void DetelteAllCookies(string domain)
    {
        if (HttpContext.Current.Request.Cookies["userToken"] == null)
        {
            string cookieName;
            int limit = HttpContext.Current.Request.Cookies.Count;
            for (int i = 0; i < limit; i++)
            {
                cookieName = HttpContext.Current.Request.Cookies[i].Name;
                HttpContext.Current.Response.Cookies.Remove(cookieName);
                HttpContext.Current.Response.Cookies[cookieName].Domain = domain;
                HttpContext.Current.Response.Cookies[cookieName].Expires = DateTime.Now.AddDays(-1);
                HttpContext.Current.Response.Cookies[cookieName].Value = null;
            }
        }
    }
