# X-CDN Header

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:\
