              Forceably remove a server from its backend, eventually killing existing connections.

              Check if a server is safe  to  remove  from  its  backend  (ie:  check  if  there's  not  existing
              connections to it).

              This  utility  has  been written by Olivier Chaze <olivier.chaze at infomaniak dot com> and Thomas
              Goirand <zigo at debian dot org> for internal use in the Infomaniak servers.

                                                                                                         hapc(1)

hapc needs an admin socket to be able to use it. So it is needed to add this to /etc/haproxy/haproxy.cfg:

       global
               stats socket /var/lib/haproxy/admin.sock mode 600 level admin
