I have a S3 bucket called "abcd" that I would like to map to a subdomain, "abcd.mydomain.com", using a CNAME.
Unfortunately I can't move files from the original "abcd" bucket to a new "abcd.mydomain.com" bucket, because it will break an existing iOs application.
My question is: is it possible to create an "abcd.mydomain.com" bucket and tell S3 that this new bucket is simply an alias to the original "abcd" bucket?
