The invention relates to a server for communicating over a client-server network. The server includes a receiver receiving a first request from a first client to establish a communication session with the server. The server also has a user session mechanism that establishes a user session in response to the first request. The server additionally includes a client session mechanism that establishes a first client session in response to the first request. Upon termination of the first client session, the server stores user session data in a memory element, which can be, for example, a database. The receiver also receives a second request to establish a communication session with the server from a second client. When receiving this second request, the user session mechanism reactivates the user session.
