public static string GetCookieVal(string sKey)
        {
            string sRe = string.Empty;
            try
            {
                HttpCookie cookie = HttpContext.Current.Request.Cookies[CookieKey];
                if (cookie != null) {
                    sRe = cookie[sKey];
                }
            }
            catch
            { }
            return sRe;
        }        public static string UserName { get { return GetCookieVal("username"); } }请问在页面中使用 UserName这个变量会有问题吗?会不会读到别人的Cookie???
