Retrying my question: What happens to sessions bound to a backend when that backend is marked dead? Will all active sessions be redirected to another live backend or will users receive a http 5xx error when they try to access the site?
My preference is they are redirected to a live backend with the risk they loose their shopping basket (the web application is a web shop).
