Since `haproxy v1.5.0` it was possible to temporarily stop reverse-proxying traffic to frontends using
set maxconn frontend <frontend_name> 0 command. I've noticed that if haproxy is configured to maintain keepalive connections between hapxory and a client then said connections will continue be served whereas the new ones will continue awaiting for "un-pausing" a frontend. The question is: is it possible to terminate current keepalive connections *gracefully* so that a client was required to establish new connections? I've only found `shutdown session` and `shutdown sessions` commands but they are obviously not graceful at all. -- With best regards, Ivan Kurnosov
