HEAD Bucket

HEAD {{baseUrl}}/n/:namespaceName/b/:bucketName/

Efficiently checks to see if a bucket exists and gets the current entity tag (ETag) for the bucket.

Key	Datatype	Description
`if-match`	string	The entity tag (ETag) to match with the ETag of an existing resource. If the specified ETag matches the ETag of
the existing resource, GET and HEAD requests will return the resource and PUT and POST requests will upload
the resource.

`if-none-match`	string	The entity tag (ETag) to avoid matching. Wildcards ('*') are not allowed. If the specified ETag does not
match the ETag of the existing resource, the request returns the expected response. If the ETag matches
the ETag of the existing resource, the request returns an HTTP 304 status without a response body.

`opc-client-request-id`	string	The client request ID for tracing.
`Accept`	string

status: OK
