- cache-control had some logic in it for private blogging + similar logic exists for members in site/app
- having it in 2 places is weird, and having it inside the mw makes the mw less generic/reusable
- instead of requiring config inside the middleware, we pass config in for the one case where this is used
- fixed tests that didn't test anything 🙈
