Cross-origin resource sharing (CORS) is a mechanism for client web applications loaded in one domain to interact with resources in a different domain. With CORS, you can selectively allow cross-origin access to your VMware Cloud Director Object Storage Extension resources.
Using the VMware Cloud Director Object Storage Extension tenant portal, you can define multiple CORS rules at the bucket level.
CORS rules at the bucket level only take effect on virtual hosted-style S3 API requests. If you access resources using path-style S3 API requests, the global CORS rules take effect.
