![]() Sessions are logically and physically distinct from Oracle database sessions used to service page requests. A user can also run multiple instances of an application simultaneously in different browser programs. The Application Express engine uses this identifier (or session ID) to store and retrieve an application's working set of data (or session state) before and after each page view.īecause sessions are entirely independent of one another, any number of sessions can exist in the database at the same time. Each session is assigned a unique identifier. ![]() While the session ID is the key to session state, the session cookie and the session record safeguard the integrity of the session ID and the authentication status of the user.Ī session is a logical construct that establishes persistence (or stateful behavior) across page views. These checks provide users with flexibility and security. Oracle Application Express assigns new session IDs during authentication processing, records the authenticated user's identity with the session ID, and continually checks the session ID in each page request's URL or POST data with the session cookie and the session record in the database. This cookie is sent by the Application Express engine during authentication and is maintained for the life of the application (or browser) session. In this example, the session ID is 220883407765693447.Īnother visible location is in the page's HTML POST data and indirectly in the contents of a session cookie. The session ID displays as the third parameter in the URL, for example: The most visible location of the session ID is in the URL for a page request. The Application Express engine establishes the identity of the user for each page request and the session ID to fetch session state from the database. A session ID is a unique number assigned a specific user for the duration of that user's visit ( session)
