            for (var i = 0; i < cookieCount; i++)

                var cookie = HttpContext.Current.Request.Cookies[i];
                if (cookie != null)
                {
                    var expiredCookie = new HttpCookie(cookie.Name) {
                        Expires = DateTime.Now.AddDays(-1),
                        Domain = cookie.Domain
                    };
                    HttpContext.Current.Response.Cookies.Add(expiredCookie); // overwrite it
                }
            }

            // clear cookies server side
            HttpContext.Current.Request.Cookies.Clear();
        }
    }
