If your Internet connection is unstable, periodically disconnecting and reconnecting, it can cause a website session to expire. When the Internet connection is lost the website connection can be terminated, resulting in a session expired message if you try to access any page after the Internet reconnects.
By using SecurityContext you can get this info in your controller code. SecurityContext context = SecurityContextHolder. getContext(); Authentication authentication = context. getAuthentication();
Answer. Yes the Session cookie expires. In addition to the 30 minute default timeout (if the visitor is idle for 30 minutes) the 'Session ID' cookie will expire at the end of an internet browser session.
Session expiration is comprised of two timeout types: inactivity and absolute. An absolute timeout is defined by the total amount of time a session can be valid without re-authentication and an inactivity timeout is the amount of idle time allowed before the session is invalidated.
Yes:
you can call HttpServletRequest.getSession(false) and you'll get a null instead of a session if there isn't one active already.
you can define a lifecycle listener (using HttpSessionListener) in your web.xml. That way you can get notified the moment a session bites the dust.
