Looking at your previous posts, i think that you are wasting your time

again, maybe answering the following simple sequence of questions:
1) Your web application server has access to some data somewhere. The
data can be any
Here's an example:
public class Downloader extends HttpServlet
{
private void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException

resp.setHeader("Pragma", "no-cache");
