Comment 3 for bug 2047052

Well S3 expects only lower case letters, see [1]

This is due to the fact that S3 bucket can be accessed via a subdomain with the bucket name. This is by AWS and also 3rd party implementations such as Ceph [2].

I am wondering if Swift would actually allow for "CoNtAiNeR" to exist alongside "container" and "CONTAINER" [3]? Otherwise I would expect the Swift library to actually normalize / lowercase the name or even through an exception.
