I need to generate download links for files that are stored on S3, but my company does not want to expose the AWS URL. Our system is developed in Java and Spring, until then the system retrieved the required file and sends it through Response, but the files are becoming too large for this to continue viable. I'm trying to work with presignedURL, I saw somewhere that it was possible to modify the generated url to a subdomain of ours and use a cname setting pointing to the URL of our S3 .s3-sa-east-1.amazonaws.com / bucket URL. .. My team and I use this page as a reference: link
In any case, this is not working. When attempting to access the modified URL, aws returns a denied access.
Would anyone help me?
