Oh, indeed!

Although the doc only mentions CORS [1] on an "exposing website page" which is not exactly related; also the mention strongly suggests using reverse proxy for CORS [1] which is an overkill and perhaps not needed if supported natively?

Also googling the question only points out to the same reverse proxy page.

Now that I know about PutBucketCORS it's perfectly clear but perhaps it's not easily discoverable.

I am willing to write a cookbook article on signed browser uploads once I figure out all the details.
