This is actually a pretty common issue. HAProxy is currently not aware of keep-alive-traffic. The routing decision is therefore based on the first HTTP-request of a TCP-connection. That's why you see the first request routed correctly. However, your browser keeps an open TCP connection which is used to send the second request if it is issued in a certain time frame. That request is then routed to the same server as the first one of that particular connection. The solution is as simple as adding option httpclose # disable http keepalive to your default section. This will simple disable keep-alive traffic. For more details of the implementation see the documentation. --Holger
