proxy_cache and X-Accel-Redirect

Hi,
I currently get requests that are resolved with an external server to a file
with X-Accel-Redirect:

for example:

/data/asd-asd-asd -> proxied to a backend -> resolves to file.xls
/data/qqq-qqq-qqq -> proxied to a backend -> resolves to file.xls
/data/123-123-123 -> proxied to a backend -> resolves to image.jpeg

I want to cache the resulting files with nginx, as the initial access is
very costly (they are accessed over the network). On first access they
should be copied to a local cache, following requests should also go to the
backend but actually serve the file from cache.

My current config:
https://zerobin.davidventura.com.ar/?0018df75a5d31f2c#Un5Eo10lo4eRnhY7ngQiHlSTErCVH/8zjRN+qS0JSl0=


Note: The files are quite large (up to 4gb)

I added the proxy_cache directives to both the requests path and the
internal path but none of them are working.

/cache/ is never populated, and the X-*-Cache headers are not present in the
response
