    res.setBufferSize(8 * 1024); // 8K buffer
    res.setContentType("text/html");
    PrintWriter out = res.getWriter();

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

    // Record the default size, in the log
    log("The default buffer size is " + size);

    out.println("The client won't see this");
    res.reset();//from w ww. j  av a2  s .  c o  m
    out.println("And this won't be seen if sendError() is called");
