First of all, this might be a basic question and I am very unsure about the terminology to use regarding this.

I currently have Servicedesk MSP installed and running on a windows 2012 server which I connect to using a URL servicedesk.mydomain.com on port 80

This works excellent.

I am now going to install Desktop Central MSP on the same server running on a different port, say 8080.

(I know that you may use Servicedesk MSP integrated with Desktop Central but this is not what I want to do right now.)

What I would like to accomplish is to connect to Desktop Central using a different subdomain, say desktopcentral.mydomain.com, and this is of course pointed to the same ip since its the same server.

I would like to not have to use the port numbers here if I can avoid it.

Is there a way to, based on the URL (subdomain) I use have the server either point me to port 80 or to port 8080?

See picture below for how I want it.
