public static void ClearClientPageCache()

HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.Expires = 0;
HttpContext.Current.Response.ExpiresAbsolute = DateTime.Now.AddDays(-1);
HttpContext.Current.Response.AddHeader("pragma", "no-cache");
HttpContext.Current.Response.AddHeader("cache-control", "private");
HttpContext.Current.Response.CacheControl = "no-cache";
}
#endregion
