Hello, We are considering moving from Nginx to Traefik as the frontend for our RGW services. Prior to putting into production I ran it through s3-tests and noticed that all of the tests involving metadata (x-amz-meta-*) are failing because they are expected to be lowercase (test_s3.py::test_object_set_get_metadata_none_to_good - KeyError: 'meta1'). Traefik / Go converts these to have the first letter uppercase (X-Amz-Meta-Key). Poking around I found https://github.com/traefik/traefik/issues/466 and it points out RFC 2616 which says these should be case insensitive. AWS S3 says "User-defined metadata is a set of key-value pairs. Amazon S3 stores user-defined metadata keys in lowercase." over at https://docs.aws.amazon.com/AmazonS3/latest/userguide/UsingMetadata.html. Is anybody using Traefik for their frontend to RGW? Do you mitigate this if so and how? Thanks for any input. Reid
