Hi,
I use the code at end of this message to strip the Jsessionid, it works very
well, however it started to have error when I call this in my T5 app:
Session session = request.getSession(false);
if (session != null) {
session.invalidate();
}
cookies.removeCookieValue(logKey);
can this problem be fixed? Thanks,
Angelo
