ForwardAuth / webstack-micro

I just pushed an example web app that highlight's Traefik's ForwardAuth middleware.
A lot of the people on this forum have asked for a realistic example of ForwardAuth and I'd like to improve its Traefik config enough to offer it as a suggestion.
I'm about to port it from Traefik v1.7 to v2.0 and wanted to check in here before starting. Any tips? Anything you'd recommend including? Would someone be open to reviewing it, or perhaps contributing?
