Thanks Davide,

domain name

Anyway the users are spread around and not on the same intranet (they
travel and use their laptop + an internet connection from hotels and so
forth).

That's why I was thinking about a proxy server (which is the only thing
which is configurable in that crappy legacy app).

Knowing this would apache + mod_proxy be enough? I really need a simple
solution, nothing complicated
