    res.setContentType("text/html");
    PrintWriter out = res.getWriter();

    int size = res.getBufferSize(); // returns 8096 or greater

    log("The default buffer size is " + size);

    out.println("The client won't see this");
    res.reset();// ww  w .  j  ava  2 s  . c o  m
    out.println("Nor will the client see this!");
