It works quite well for something that's impossible :-)
I don't know that much about Borderware kit, but I know that the server I'm
accessing is connected to one of the auxiliary ports of the Borderware
firewall. The BW box has been configured to pass certain traffic  to
the auxiliary server when I use a particular hostname. The forwarding
doesn't occur when I try to access the machine by IP, or via an alias.
 In this case it's traffic to and from our source code repository, but
it seems you can do the same trick for any port.
