Abstract:
A server apparatus includes a registration table for storing identification codes and access times of clients; a registration-controlling unit for controlling the identification codes in the registration table; an authenticating unit for authenticating the clients with reference to the registration table; and a clock for providing a current access time. When a client submits a registration request, the registration-controlling unit registers the identification code of the client and the current access time in the registration table. When a client submits an access request and when the authenticating unit confirms existence of the identification code of the client in the registration table, the access request is accepted and the access time of the client in the registration table is updated with the current access time. At least one client having no access for a predetermined period is removed from the registration table.
