# 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:\

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://clients.medianova.com/products/performance-cdn/dynamic-content-acceleration/advanced-configuration/headers/origin-host-header.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
