With your current config, HAProxy will add a "Connection: close" header to responses. However, since you mentioned you are running this in an OpenShift environment, there might (and probably is) be another layer of proxies involved between your HAProxy and your client. Since you are speaking plain HTTP here, this other proxy might chose to use keep-alive connections towards the client, similar to how HAProxy's option http-server-close works. In that case, you would have to change the configuration of this other proxy too. Best, Holger P.S. HAProxy 1.4 is OLD and receives only critical fixes now. You should seriously consider upgrading to a newer version. The current stable version if 1.7.26. At the very least, you should upgrade to the latest 1.4 version 1.4.27 has fixed 83 known bugs since 1.4.22. See https://www.haproxy.org/bugs/bugs-1.4.22.html for details.
