My hero

thank you very much for solution :)

Thank a lot man!

Thank, you bro!
It helps me a lot. With your solution, i could turn my javascript's integrations more rich. I only add "response.setStatus(int n)" in onInvalidSessionDetected file to facilitate in jQuery.post.

:)

You saved my life ;)

Great work, however, you shouldn't put the RedirectStrategy code inside your implementation of "InvalidSessionStrategy", however you should delegate the work to an implementation of RedirectStrategy instead. (exactly as SimpleRedirectInvalidSessionStrategy works.)

Great work, however, I added in the file of config
and in the face-config
< lifecycle>

web.util.CacheControlPhaseListener< /phase-listener>
< / lifecycle>

public class CacheControlPhaseListener implements PhaseListener {
private static final long serialVersionUID = 2475683599960651934L;
@OverRide
public void afterPhase(PhaseEvent event) {}

@Override
public void beforePhase(PhaseEvent event) {
    FacesContext facesContext = event.getFacesContext();
    HttpServletResponse response = (HttpServletResponse) facesContext
            .getExternalContext().getResponse();
    response.addHeader("Pragma", "no-cache");
    response.addHeader("Cache-Control", "no-cache");
    // Stronger according to blog comment below that references HTTP spec
    response.addHeader("Cache-Control", "no-store");
    response.addHeader("Cache-Control", "must-revalidate");
    // some date in the past
    response.addHeader("Expires", "Thu, 01 Dec 1994 16:00:00 GMT");

}

@Override
public PhaseId getPhaseId() {
         return PhaseId.RENDER_RESPONSE;
}

}

otherwise many problems appear.
what do you think ?

Worked like a charm, thank you!

Thanks!!!
