Non-Persistent and Persistent Sessions

SiteMinder also provides the ability to configure a persistent session to provide Windows security context functionality and support for Federated Web Services. A persistent session is one in which a SiteMinder cookie is maintained in a SiteMinder session store, in the memory of the web browser, and optionally the hard disk.

Before you implement persistent sessions, consider the following:

• Persistent sessions are configured on a per realm basis.
• Persistent sessions should only be used where necessary. Using session services to maintain sessions has an impact on system performance.

Note: For more information about enabling and configuring session services, see the Policy Server Administration Guide.
