We should not publish these two methods :

ServletResponseUtil.getRanges(HttpServletRequest request, HttpServletResponse response, long length)
ServletResponseUtil.write(HttpServletRequest request, HttpServletResponse response, String fileName, List<Range> ranges, InputStream inputStream, long fullLength, String contentType)

since they are only used in current class, and the same function can be done by invoking ServletResponseUtil.sendFileWithRangeHeader().
