Session support
Information entered by a user in a Web app is often needed throughout the app. For example, a user selection might be used to determine the path through future menus or options to display content. This information is kept in a session.
A session is a series of requests to a servlet that originate from the same user. Each request arriving at the servlet contains a session ID. Each ID allows the servlet to associate the request with a specific user. The WebSphere session management component is responsible for managing sessions, providing storage for session data, allocating session IDs that identify a specific session, and tracking the session ID associated with each client request through the use of cookies or URL rewriting techniques.
When planning for session data, there are three basic considerations:
Application design
Session tracking mechanism
Session storage options.
The following sections outline the planning considerations for each.
