Return file as octet-stream as part of an API response.

[NachoPonisio]

Hi folks,

I'm pretty new at using Cask, so I apologize beforehand for my lack of knowledge.

The problem follows. I'm trying to create an API resource that must return a large file stored in secondary memory as part as its response, as octet-stream. This is not the same use case as serving a static resource, as described in the documentation. I haven't been able to find any similar examples in the docs.
I'd appreciate any input from the community that could point me in the right direction.

Thanks in advance.
Ignacio
