title: OpenAM call back in case of load balancer
body: <p>While going through the openAm document I found that when a session is invalidated by admin, openAm notifies the agent about this, but suppose I have multiple copy of my application which are situated in geographically distributed location sitting behind a load balancer, how will the particular agent will be notified in case of a session invalidation happening, I guess sticky session wont help in this scenario as no request is going from my application side. </p>
