 ### Step 4: Test the sample app
 
 When you bring up the app in a new browser session the banner on the web page will say  **Hello stranger**. A new HTTPSession object is created and it's state is replicated to all the pods. When the app encounters an existing HTTPSession object the banner message will change to **Welcome back friend**.

 ## Summary
 Congratulations. You used the **session-cache** feature in WebSphere Liberty along with the Open Source **Infinispan Data Grid** to demonstrate HttpSession replication in OpenShift. This allowed you to  deploy  a stateful application in a stateless manner (i.e each application pod can be deleted or replaced at anytime without losing application state).
