Depending on whether the bucket name is included in the hostname in the HS3 request, the request line for a request to retrieve an object has either of these formats:
•With the bucket name included in the hostname:
HEAD /object-name[?versionId=version-id] HTTP/1.1
•With the bucket name following the hostname:
HEAD /bucket-name/object-name[?versionId=version-id] HTTP/1.1
