Get Object
GET /{object_name}[?versionId={version_id}]

ECS also enables a specified byte range, or multiple specified byte ranges to be downloaded.URL Format
Host Style: http://bucketname.ns1.emc.com/{object_name}[?versionId={version_id}]
Path Style: http://ns1.emc.com/bucketname/{object_name}[?versionId={version_id}]
Alternatively, both styles can specify the namespace using the x-emc-namespace header.
