Servlets in Java have an HttpSession object which you can use to store state information for a user. The session is managed on the client by a cookie (JSESSIONID) or can be done using URL rewrites. The session timeout describes how long the server will wait after the last request before deleting the state information stored in a HttpSession.

The scope is per browser instance, so in the example you give logging in from two different pcs will result in two session objects.
