About this task

The Liberty profile does not include session replication. However, if you use WebSphere® eXtreme Scale with the Liberty profile, then you can replicate sessions. Therefore, if a server fails, then application users do not lose session data. When you add the webApp 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. You can configure a web application server so that, when the web server receives an HTTP request for session replication, the request is forwarded to one or more servers that run in the Liberty profile.
