host with a different resource/path

The problem that I am stuck into is very simple yet complicated for me.
I would like to know how can I add a different path of the service that is being used.
I have a service running on server which is listening to port 3000 (i.e. localhost:3000) and I have another service which is listening request on port 3000 but on a different path (localhost:3000/Chat) 

How do I change the path ?
