Justin,
We had two different apps that needed to listen on the same port, 443.
So we created a virtual IP to handle one of the apps.

That's what I assumed, and what Wikipedia shows. OTOH I received a private reply saying that ports must be unique across an entire server. I guess I'll build a test and find out.
Thanks guys,

Assuming my server IP is 9.8.7.6, can different services listen on
9.8.7.6:54321 and 127.0.0.1:54321?
Yes, as long as the services can bind to a specific IP address and don't bind to all addresses (0.0.0.0).
