an incoming connection won't trigger a name resolution. the name resolution is simply used to update a server's IP address upon time without restarting HAProxy. > How HAproxy test / health check ips of exist sessions when configured > working with DNS? I've already explained this twice. I might be not clear enough. Let me rephrase: - server's health check triggers name resolution (after a 'valid' period timeout has expired) - if the IP address currently affected to the server is found in the DNS response, then no changes otherwise, HAProxy will apply the first IP address returned by the DNS server > I guess that new session will get ip from the latest DNS response by health > check i.g 10.0.0.4, right ? no, if the DNS server changes its response, it means the server has change its IP address. existing sessions will time out while new ones will be established to the new IP. It doesn't affect persistence at all. Baptiste
