balancer redirects or proxy?

[gdewey]

I havent isntall the demo of the balancer but I have a basic question. Does the balancer proxy the request to the target (origin) webserver or it just redirects?.. in other words, the browser renders at the end the html content from the balanced server or the balancer it self.
