About Using Zero as a Session ID

When users access Oracle Application Express application pages, numerous links containing session IDs become visible in the Web browser's location window. If the application is publicly accessible and the user communicates one of these links to another application user, for example by using email or a messaging service, the recipient can use the link and immediately begin sharing the original user's session. This can have a negative effect on both users as they use the application and lead to unpredictable, hard to reproduce screen behavior. To prevent this, Oracle recommends the use of the Zero Session ID feature for all applications where users are not required to provide login authentication.
