S3 Gateway
Supported operations
The gateway supports the core S3 verbs needed for daily file management
plus multipart upload. Anything not in the table below is not implemented.

| HeadBucket | HEAD | /<bucket> | 200 if the bucket exists, 404 NoSuchBucket otherwise. |
| CreateBucket | PUT | /<bucket> | No-op. Buckets map to existing connections; a 200 is always returned. |
