    if (xsrfSessionToken == null) {
        Random r = new Random(System.currentTimeMillis());
        long value = System.currentTimeMillis() + r.nextLong();
        char ids[] = session.getId().toCharArray();
        for (int i = 0; i < ids.length; i++) {
            value += ids[i] * (i + 1);/*from   w  w w. ja va2 s .com*/
