Can I do this and how to do it?

I have one secure gateway and two GMS servers that serve two different
departments (two Groupwise systems).

I want to use only one secure gateway. Can I setup the two GMS servers and
configure only one secure gateway? If yes, how can I route requests from
Internet to reach the right GMS server?

For example: gms.mycom.com/server1 (Internet DNS name) must routes to
gms1.internal.com (Internal network dns name) and gms.mycom.com/server2
must routes to gms2.internal.com. I can also use gms1.mycomp.com that
routes to gms2.internal.com and gms2.mycomp.com that route to

Does it make sense and how to configure the SG?

Thank you.
