Session table

The session table enables an application to manage and access session and sub-session data. For an application to be aware of a session, it must have a corresponding entry in the table and a context. Each session in the table is a hash table that contains information about the session. This information includes its relationship with another session (as the parent session or sub-session), a reference to the session context, and a reference to the HttpSession object that manages the session.

For a description of the attributes, see Session entry attributes. The server maintains the table in memory only unless session persistence is enabled.
