# Origin Host Header

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:\
