      Chimère uses a virtual host configuration. A specific hostname should be

      For instance, you should set "my_chimere.my_domain.net" to have a
      Chimère responding to "http://my_chimere.my_domain.net/".

      Of course DNS configuration should be done to match this hostname with
      this server.
