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.
