Answer 1

When session expired your have to add some information to response for example a cookie "sessionExpired=true" and sent it to your client with response.

Then you have to render your confirmDialog everytime when you find in HttpServletRequest object that cookie.

I am understanding that you expected from user to press confirmation button and it’s a only way to pass through your popup, yes?
So then when user press button just replace cookie from request (for example by changing it’s expiration date to some past value) and with next user request cookie won’t come and your app won’t display that popup.

By replacing Cookie from request I mean something like this:

Map<String, Object> requestCookieMap =
    FacesContext.getCurrentInstance().getExternalContext().getRequestCookieMap();
Cookie sessionExpiredCookie = (Cookie) requestCookieMap.get("sessionExpired");
sessionExpiredCookie.setMaxAge(0);
