HEAD Object

The HEAD Object operation retrieves metadata from an object without returning the object itself. This operation is useful if you are interested only in an object's metadata. To use this operation, you must have READ access to the object. A HEAD request has the same options as a GET operation on an object. The response is identical to the GET response except that there is no response body.

Syntax Example

HEAD https://appliance:443/s3/v1/export/share_mount_point_path/bucketname/objectname
