Re: how http-server-close work?

It will work as you said, if you have not enabled cookie persistence. (cookie line in your backend conf).

by default, without http-server-close option, HAProxy will "tunnel" requests and responses.
It will be able to analyze only the first request, taking rooting decision, then all following requests will have to follow the same route path.

Using http-server-close, HAProxy is able to take routing decision for the HTTP connection, so, objects can be downloaded from any server in a farm.

When you enable cookie persistence, then HAProxy will bypass the balance algorythm, since it already knows how to route the request.
