Host apps same port different URLS

I have an application that is listening on a predefined port. I have configured it to use port 443, so that the user can just connect to a url.

Now I would like to have two instances of them running while still being available through the default port.

e.g.:

from example.com:443/one to example.com:30001
from example.com:443/two to example.com:30002

Is there a way (like reverse proxy) to set this up? And if so: is there a blog or tutorial I could follow through? I am fairly new to working with linux.
