Hi Mark, It depends on the options you have enabled on HAProxy, and in some cases, on the server itself. The options I'll speak about are "http-server-close" and "httpclose". If none of them are set in your configuration, then you're in the tunnel mode, which means HAProxy will analyze the first request then maintain opened a tunnel between the client and the server, where every data being transferred won't be analyzed. In this mode, this is up to the server to decide when to close the connection. If you setup httpclose, then HAProxy will close the TCP connection after each request for both client and server, announcing the HTTP header "Connection: close". If you setup http-server-close, then HAProxy will use HTTP keep alive to maintain the TCP connection opened on the client side only. On the server side, a new TCP connection will be opened per each HTTP requests. I don't understand your last question. Could you be clearer? Baptiste
