The mechanism of request.getSession() has the capability of tracking the session ID from URL or cookie. The session cookie, if presence, contains the session ID.

You do not have to worry when the ID is readed.

Just know that the method "request.getSession();" brings you the client session.

And by default if is no session was created before (like first time in the page, timeout), it will creat a new session for you.
