Abstract

This invention relates to the handling of sessions between clients and services. The invention is to use a centralized element for keeping and managing information of the sessions. Each session (client) is identified by a session-specific ID. The application in the server to which the client is connected checks the session's, i.e. the client's, ID from a centralized element, called session management, by sending the ID to the session management. The session management checks that the ID is correct. If it is, the session management sends the session information of the client to the application. When the session information changes from the act of the client and/or the application, the application updates the changes to the session management.
