A prefix used to restrict the results returned when listing objects.
Object Hierarchy Traversal
By using the ObjectDelimiter and ObjectPrefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:
|ObjectPrefix Value||ObjectDelimiter Value||Objects Returned||Prefixes Returned|
This property is not available at design time.
