Configure a WebSEAL instance on a cluster member to use the distributed session cache

For nodes that are in the distributed session cache server cluster, use the local management interface (LMI) to configure WebSEAL to use the distributed session cache.

For an appliance-based WebSEAL instance that is internal to the distributed session cache server cluster, the configuration occurs automatically when we enable the distributed session cache in the LMI.

Steps

  1. In the LMI, select Web > Manage > Reverse Proxy.

  2. Select the WebSEAL instance to use the distributed session cache.

  3. Click Edit.

  4. Select the Session tab.

  5. Select Enable Distributed Session Cache.

  6. Save and deploy the configuration changes.
  7. Restart the WebSEAL instance.

WebSEAL is automatically configured to use the distributed session cache. WebSEAL uses SSL to communicate with the distributed session cache.

A message is printed in the WebSEAL log regarding the synchronization between the local session cache and the distributed session cache. No further manual configuration is required.


What to do next

We can use the local management interface to view and manage the servers in the replica set. Go to Web > Manage > Distributed Session Cache.

The dscadmin tool is also available for session management. For information about this tool, search for "dscadmin command" in the Configuring Web Reverse Proxy topics in the Knowledge Center.

By default, all WebSEAL instances are added to the default replica set. To group the WebSEAL instances into separate replica sets, change the name of the replica set associated with each instance in the WebSEAL configuration file. For information about this configuration, see Replica set configuration.

We can configure the maximum concurrent sessions policy, as described in Set the maximum concurrent sessions policy. By default, there is no concurrent limit.

We can use the steps that are described in Test the configuration to verify the environment is working correctly.
