All the dependencies we have seen are a fixed function or class.

But there could be cases where you want to be able to set parameters on the dependency, without having to declare many different functions or classes.

But we want to be able to parameterize that fixed content.

Any incoming request to `http` or `ws` will be redirected to the secure scheme instead.
