Perspective Client redirect in load balanced front end cluster

In this image, what is the “Load Balancer” shown in the layout? Can anyone explain how a browser client is automatically redirected when one of the load balanced gateways fail. Is this handled in the “Load Balancer” box in this diagram? I have noticed in the perspective workstation setup there is a client fallback you can setup, but it only provides an option for a single fallback. Any information is appreciated?

Thanks,

Frank

In a typical HAProxy setup, all of the browsers point at one domain name. They aren’t redirected to the different front-ends, the load balancer simply remembers which front-end it assigned to a particular browser and keeps forwarding there. (Until a front end dies–then the user has to restart a session on the next available front-end.)
