Origin Host Header

Learn how Origin Host Header customizes the Host header sent to your origin for dynamic traffic.

The Origin Host Header feature for Dynamic Content Acceleration operates the same way as in Static Content Delivery. It allows CDN edge servers to overwrite the Host header in origin requests with a custom domain you specify. This is essential for virtual hosting environments, multi-tenant systems, and origins that rely on hostname-based routing or validation. Viewer-facing responses and cache behavior remain unchanged.

For configuration details, header behavior, and examples, refer to the main documentation: Learn more in the Origin Host Header documentation.
