Amazon S3 CORS headers only show during OPTIONS (preflight) and not during GET request

Question

I have an S3 bucket with the following CORS config.

Answer 1

With your curl -iI option you will be doing a HEAD request and not a GET request. So you will not get the CORS headers. To simplify testing add <AllowedMethod>HEAD</AllowedMethod> to your CORS configuration and you'll get the expected results.
