If you know for a fact that they are http DDos you and its not just a port flood (loading any page on a certain port) then do a server side redirect using htaccess or on other servers by server configuration. Force any 404 error to be redirected to a different site or IP (can even be the Hackers IP) so that it never reaches your actual script or decoded html page.
It will still cause some or minor delay in resolving your pages, but it will barely be noticeable.
