Use cookies to store the session id. Then the browser can be associated to only one session at a time. Use the session to store whether the user logged in. On the login page ask the session whether the user already logged in.
As with all network communication, this requires a certain amount of trust in the transmitting end (i. e. the Browser). It should therefore not be used for high risk scenarios. It’s, however, the best you can get.
