# CORS Header

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:\
