IBM MobileFirst Session Affinity

Environment Details:
IBM MFP 7.1.0.00.20160401-2103
IBM WAS Liberty 8.5.5.5

Setup:
1. MFP App is deployed in two Liberty servers.
2. Mobile devices can access the App via Webserver and the requests are routed on round-robin fashion properly.

Device:
1. Android
2. IOS

Problem:
1. User has logged into the App and accessing the Adapter.
2. These adapters are protected by Security test.
3. But still the request is routed to Liberty server's as round-robin by webserver.
4. Ideally, the request should be forward to the server where it is authenticated.

Configuration:
1. In authenticationConfig.xml - Securitytest & realm are defined.
2. Login initiates via WL.client.Login({realmName}); realmName - Mapped in security Test
3. Adapters are protected with the Security test defined in authconfig.xml
4. Liberty Server - Manual & Unique cloneID is provided for both server in httpsession of server.xml
5. In Webserver, plugin-cfg.xml is configured for session affinity along with cloneID of each server.

 <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid"
 Name="/wladmin/*"></Uri>

Did I miss something? Why the requests are routed by WebServer to both the liberty servers after authenticating.

Note:
1. Plugin-cfg.xml is generated via jconsole.
2. Liberty Farm is configure and active.

In MFP 7.1 by default it is session independent. Still we support session dependency but for this you need to configure. Please check this https://www.ibm.com/support/knowledgecenter/SSHS8R_7.1.0/com.ibm.worklight.dev.doc/devref/c_overview_session_indep.html for more details.

Note: If your system is operating in session-independent mode and you choose to scale back or scale up any number of servers, the user experience is unaffected. This is the advantage.
