Cross-Origin Resource Sharing (CORS) is a mechanism that allows code running in a browser (JavaScript for example) to make requests to a domain, other than the one it was originated from. OpenStack services support CORS requests.
For more information, see cross-project features in OpenStack Administrator Guide, CORS in Dashboard, and CORS in Object Storage service.
For a complete list of all available CORS configuration options, see CORS configuration options.
