Disconnects means his/her internet connection disconnected, then in that case browser stores the cookie information in the browser. Again when internet connection is up , and user logs in the same site(url). based on cookie information, server validates is the session valid, if yes it shows the session data or the user as logged in (without asking the credential again).

Now comes to your question, the best way to track the session is through using session object.
