How to check if a response is redirect response?

[juniorforlife]

Hi @sergiodxa, in your article https://sergiodxa.com/articles/throwing-vs-returning-responses-in-remix,
you mentioned

Throwing a response can cause two effects, depending on whether the response is a redirect.

1. If you throw a redirect response, Remix will follow the redirect as usual.
2. If you throw a non-redirect response, Remix will render the CatchBoundary component of the route (or nearest parent route) and pass the response data to the UI with the useCatch hook.

But how do we check if a response is a redirect response or not?

If you have a Response object check if status is a redirect one, and if the headers has the Location header, if both things are true the response is a redirect.

How do I do this inside of root.tsx loader? attempting to access response headers is throwing an error.
