trap and handle session timeout

[drellim]

I have written an interceptor according to what I found in another thread opn this forum to catch session timeouts.

    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        HttpSession session = request.getSession();
        session.
        if (session == null) {
            request.setAttribute("timeout", "Your session has timed out. "
                    + "Please log in again if you want to continue to use FI-RACE.");
            response.sendRedirect("/login.jsp");
            return false;
        }
        return super.preHandle(request, response, handler);
    }

this interceptor gets called, but the session is never null.

Does anyone have any suggestions as to what I need to check to know that the session has timed put?

HttpSession session = request.getSession();

This creates a session if it doesn't already exist, hence why session is never null.

request.getSession(false) will only return a session if it already exists.

I think I've tried getSession(false) without success. I will have another go when I get a chance
