Overview: Manage Access Sessions and Subsessions

BIG-IP Next Access allows you to monitor all the active user sessions and subsessions on the instance. You can query for a summary of all active sessions or subsessions or a specific session or subsession. Additionally, you can terminate an unwanted existing session or subsession and force the end-user to authenticate on the subsequent request.

Managing session and subsession information helps you with the following tasks:

  • Create real-time utilization reports.

  • Provide complete visibility into all session or subsession-related information.

  • View variables related to a session or subsession.

  • Provide different outcomes for policies based on the values in the session variables.

  • Determine which resources to assign to users.

  • Terminate unwanted sessions or subsessions.
