Creating a local domain name for application server, on a box where port 80 is already in use

Question

I have a box running application server running on port 8500 and a web server on 80. I am trying to create a local domain name for the application server on 8500. I realize you cannot create a DNS record outside of port 80. However, I already have a web server on 80. Is there a good solution for this?

DNS A/CNAME records and ports are not related. Port 80 is just the default port for HTTP used by clients (e.g. browsers) and it's entirely possible to host one service at http://example.org:80 and something else on http://example.org:8500.

If you don't want to use the port designation in the URL, you could configure your primary web server as reverse proxy that forwards http://example.org/appserver to http://example.org:8500, so both servers are seen as one acting on the same port (80) by the clients.

The technology you are looking for is a Reverse Proxy. We have lots of Q&A about it already.

I think this answer could be better if it explained why DNS is not what he's looking for, and why a reverse proxy would work. – erjiang Sep 01 '16 at 14:45
If you think that then do it. – user9517 Sep 01 '16 at 14:52
