From the documentation: ,---- | By default HAProxy operates in a tunnel-like mode with regards to persistent | connections: for each connection it processes the first request and forwards | everything else (including additional requests) to selected server. Once | established, the connection is persisted both on the client and server | sides. Use "option http-server-close" to preserve client persistent connections | while handling every incoming request individually, dispatching them one after | another to servers, in HTTP close mode. Use "option httpclose" to switch both | sides to HTTP close mode. "option forceclose" and "option | http-pretend-keepalive" help working around servers misbehaving in HTTP close | mode. `---- -- Vincent Bernat ☯ http://vincent.bernat.im Make sure input cannot violate the limits of the program. - The Elements of Programming Style (Kernighan & Plauger)
