CORS Header

Learn how CORS Header controls cross-origin access behavior for dynamic HTML responses.

The CORS Header feature for Dynamic Content Acceleration operates the same way as in Static Content Delivery. It allows CDN edge servers to set or override the access-control-allow-origin header for HTML responses when you want to explicitly control which origins may access your resources. By default, the CDN forwards CORS headers returned by your origin; enabling this feature instructs the CDN to generate or override the header instead, using either a wildcard or a defined allow list.

For configuration details, allowed domain behavior, and examples, refer to the main documentation: Learn more in the CORS Header documentation.
