Mapping port traffic

This is more of a TCP/IP issue (I think) than iSeries web server issue but
here is the question:

I have a Tomcat server and a standard Apache server running on our iSeries.
The default config has port 80 traffic on mycompany.com going to the apache
server but I want myhost.mycompany.com traffic to map back to port 9095
where Tomcat is listening.  So, I want to make a distinction between port 80
and port 9095 traffic by host name. I want myhost.mycompany.com to go to
10.0.0.101 on port 9095 while the mycompany.com traffic to go to 10.0.0.100
on port 80.  How do I do that? Do I need to qualify the host for the port 80
traffic as well? (e.g. mydefaulthost.mycompany.com goes to port 80 and
myhost.mycompany.com goes to port 9095)

I have a quiet bell ringing in my head about how to do this but I don't have
enough to get started.  I know this is simple, just can't quite remember the
rules.

Any pointers?
