First, you will need to request a "master" instance of Apache Frontend with
"domain" parameter, like :

Then, it is possible to request many slave instances
(currently only from slapconsole, UI doesn't work yet)

Notes
=====
It is not possible with slapos to listen to port <= 1024, because process are
not run as root. It is a good idea then to go on the node where the instance is
and set some iptables rules like (if using default ports)::
