There should be a way to attach metadata to AWS objects uploaded by Publii, especially http response headers like content type and cache-control. I can add metadata to an object using AWS’s web interface, but each time Publii uploads a new copy of the file, the metadata is erased. In a non-Publii project using AWS S3, our team uses a Python script that adds headers each time a file is uploaded to a bucket, based on file type. Something like that in Publii would be very useful, perhaps with settings for home page, posts, assets, and media.
