Thanks for the explanation, it's very enlightening to someone (me) who's never used haproxy. For front-end load balancing, I've been using Varnish. Is HAProxy also better at http load balancing than Varnish as well as nginx, do you know?

I use both, as varnish does caching well. Two haproxy servers where one is a fail over. varnish on both.
