We have some good news for people using CDNs or bucket names that are not well-formed. As of today, we are supporting a new parameter called
url_prefix for our /s3/store Robot.
Before, we would always return URLs prefixed with
<bucket> is the name of the S3 bucket in which we stored the file.
This new option now allows you to define any prefix, for example
"https://E123456.cloudfront.net/", in case that is the name of your CloudFront domain.
