Chris-
Haproxy is a software proxy that can do the right thing and not
overload mongrels. But it is not a webserver. I have used it behind
nginx. So nginx or apache proxy to one haproxy and then haproxy does
the load balancing in a more inteligent way then apapche ro nginx can
do right now.
But Igor the author of nginx said that he will be adding a max-load
to the ngixn proxy module which you could set to one and then ngxin
would queue requests instead of mongrel and only send requests to
mongrels that are not busy. This will be the best option with the
least moving parts once he adds this feature.
