Enabling the eXtreme Scale web feature in the Liberty profile
You can enable the web feature to use HTTP session failover in the Liberty profile.
About this task
The web feature is deprecated. Use the webApp feature instead. When you add
the webApp feature to the server definition and configure the session manager, you can use session
replication in your WebSphere® eXtreme Scale applications that run in the Liberty.
When you install the WebSphere Application Server Liberty, it does not include session replication. However, if you use WebSphere eXtreme Scale with the Liberty profile, then you can replicate sessions so that if a server goes down, the application users do not lose session data.
When you add the web feature to the server definition and configure the session manager, you can use session replication in your eXtreme Scale applications that run in the Liberty profile.
