Task overview: Managing HTTP sessions

IBM WAS provides a service for managing HTTP sessions, Session Manager. The key activities for session management are summarized in this topic.

Before you begin these steps, make sure that you are familiar with the programming model for accessing HTTP session support in the applications following the Servlet 3.0 API.


  1. Plan your approach to session management, which could include session tracking, session recovery, and session clustering.

  2. Create or modify your own applications to use session support to maintain sessions on behalf of web applications.

  3. Assemble the application.
  4. Deploy the application.
  5. Ensure the administrator appropriately configures session management in the administrative domain.
  6. Adjust configuration settings and perform other tuning activities for optimal use of sessions in the environment.
