CORS in Cloud CDN

Yandex Cloud CDN supports cross-domain requests via CORS (cross-origin resource sharing).

In the resource settings, you can:

• Allow CORS requests with any origins (the Origin header values): Set the Access-Control-Allow-Origin header to * or to the Origin header’s value in the request.
• Allow CORS requests for specific origins: Set the Access-Control-Allow-Origin header to the value of the Origin header in the request, but only if it is listed as allowed in the settings.
• Deny CORS requests: Disable adding the Access-Control-Allow-Origin header to responses.

CORS settings apply to all files of the resource.

When you use the EdgeCDN provider, the maximum number of CORS domains when responding to client requests is 20. Learn more about limits and restrictions.
