Specific behaviors compared to AWS API :
Creation of buckets using names with fewer than three characters fails with :
When creating a bucket or object with empty content, cegedim.cloud Object Storage Service returns 400 invalid content-length value, which differs from AWS which returns 400 Bad Request.
Copying an object to another bucket that indexes the same user metadata index key but with a different datatype is not supported and fails with 500 Server Error.d
When listing the objects in a bucket, if you use a prefix and delimiter but supply an invalid marker, cegedim.cloud Object Storage Service throws 500 Server Error, or 400 Bad Request for a file system-enabled bucket.
However, AWS returns 200 OK and the objects are not listed.
For versioning enabled buckets, cegedim.cloud Object Storage Service does not create a delete marker when a deleted object is deleted again.
This is different from AWS, which always inserts delete marker for deleting deleted objects in versioning enabled buckets.
This change in behavior is only applicable when the deleted object is deleted again from owner zone.
When an attempt is made to create a bucket with a name that already exists, the behavior of cegedim.cloud Object Storage Service can differ from AWS.
AWS always returns 409 Conflict when a user who has FULL_CONTROL permissions on the bucket, or any other permissions, attempts to recreate the bucket. When an Object User who has FULL_CONTROL or WRITE_ACP on the bucket attempts to recreate the bucket,
cegedim.cloud Object Storage Service returns 200 OK and the ACL is overwritten, however, the owner is not changed. An Object User with WRITE/READ permissions will get 409 Conflict if they attempt to recreate a bucket.
Where an attempt to recreate a bucket is made by the bucket owner, Object Storage Service returns 200 OK and overwrites the ACL. AWS behaves in the same way.
Where a user has no access privileges on the bucket, an attempt to recreate the bucket throws a 409 Conflict error. AWS behaves in the same way.

For file system-enabled buckets, / is the only supported delimiter when listing objects in the bucket.
GET Bucket cors
GET Bucket acl
GET Bucket lifecycle
Only the expiration part is supported in lifecycle.
Policies related to archiving (AWS Glacier like) are not supported.
Lifecycle is not supported on file system-enabled buckets.
GET Bucket policy
GET Bucket Object versions
GET Bucket versioning
HEAD Bucket
List Multipart Uploads
PUT Bucket
Where PUT is performed on an existing bucket, refer to Behavior where bucket already exists.
PUT Bucket cors
PUT Bucket acl
PUT Bucket lifecycle
Only the expiration part is supported in lifecycle.
