Thank you. In the servlet, it sets the content type:

                response.setContentType("video/mp4");
                
and content length and cache control:
                response.setHeader("Content-Length", Long.toString(length) );
                response.setHeader("Cache-Control", "max-age=3600");

Is that enough?
