X-CDN Header

Learn how X-CDN Header adds identification metadata to origin requests for dynamic traffic.

The X-CDN Header feature for Dynamic Content Acceleration operates the same way as in Static Content Delivery. When enabled, CDN edge servers include the X-CDN header in origin requests, allowing your origin to identify and log CDN-proxied traffic. This header is inserted only on the origin-facing request path and does not modify viewer responses, caching behavior, or delivery logic.

For configuration details, header behavior, and examples, refer to the main documentation: Learn more in the X-CDN Header documentation.
