    resp.setCharacterEncoding("UTF-8");
    PrintWriter pw = resp.getWriter();

    HttpSession session = req.getSession(true);
    session.invalidate();

    // Ugly but the easiest way to test of the session is valid or not
    boolean result;
    try {
        session.getCreationTime();
        result = false;
    } catch (IllegalStateException ise) {
