So this is something I’ve come across a few times lately.
I have a root level app:
and a backend app with shared sessions at:
But I was thinking it wouldn’t be too hard to extend the current “attach” concept so that you could say “this app is a child of example, use
admin as the subdomain”.
The result would be:
Main app: example.fly.dev
Admin app: admin.example.fly.dev
Hopefully that makes sense
