 # Optionally set the access policy for uploaded files. The default is "private".
 # Even with "private", update clients receive access to the files via presigned
 # S3 URLs. Note however that the associated requests to S3 incur a performance
 # overhead. To avoid it, set AWS_S3_CUSTOM_DOMAIN below.

 # Optionally supply a CDN domain. You can set this to <bucket>.s3.amazonaws.com
 # to avoid the performance overhead of presigned URLs. This requires that the
 # files in the bucket are publicly readable. For example, via
 # AWS_DEFAULT_ACL=public-read.
