Allow flexibility to have different upload and download host names

[fishcakeday]

In the current form, the protocol is limited to small file sizes if one chose to utilize CDN. Traditionally, CDNs were not built to accept PUT/POST requests with the large body, and that trend is not likely to change, while potentially increasing the costs of the hosting service to accommodate for the unified host name. My main question is, is there a room to incorporate alternation in the host name for the PUTed files, or allow any sort of split?

maybe, although it would be difficult to do without introducing a sitemap / metadata endpoint

It might be possible to use a 301 or 302 redirect on the /upload endpoint but I don't know if that would cause issues for any clients

301/302 convert all requests to GET per RFC. 307/308 maybe the way but hard to say if it’s supported widely
