[keycloak-user] Admin URL configuration

Hello, I have a question about the Admin URL configuration for an OIDC client. I have an application deployed on Wildfly 10.1. This application is not distributable, stateful and relies on sticky session (using the JSESSIONID cookie). Now on the same machine I have 2 wildfly instances. Question is what value should I provide in the for the Admin URL? I see that we have this ${application.session.host} but AFAIU this will not help as the host will be the same for both. Ciao.
