Usage on Heroku

[kmcq]

Hello! Thanks so much for writing this gem.

The examples mention localhost and following them I got this set up for my local dev environment quite easily. However, I'm not sure what to use a config for when I've deployed the app (we're using Heroku). I'd be happy to write up and make a PR for the README for how to do this if you could point me in the right direction.

Thanks!

I'd be interested in this as well.

To get this working on Heroku, we'd need to be able to dynamically specify the port that the proxy runs on, as Heroku provides the PORT environment variable that it expects your application to service requests on.

The actual server (e.g. Puma) port could be derived from that, static, or random, but we'd need to be able to reliably tell the proxy what port it is on.

I think, ideally, you'd bind the server to a unix socket and have the communication between the proxy and the application server be via that socket.
