Is it possible to have the redirect_uri contain a specific port?

For example: example.com:8080

Assuming that example.com is my registered domain, is the 8080 allowed? I have tried to put it as part of my OAuth Domain, but get this error:

OAuth Domain should not contain protocol or port

If I leave the port off, it does attempt to redirect properly, but my application will not be living on my main web server.
