I'm tuning a haproxy server (version 1.5-dev22). Each url manage has today a backend with only one server (previously 2), so there no longer loadbalancing. Each backend has the option "httpclose" setted up, it also in the defaults options.
I want to activate the keepalive on it, so I will delete the httpclose in the default option and backend, but i'm trying to look for the best : no httpclose at all, or http-server-close. "http-server-close" will be better for loadbalancing only ? It would better for me to only set "timeout http-keep-alive" to maintain connection from client to server ?
