# Referrer Access Policy

> Allow or deny CDN requests based on the HTTP Referer header to prevent hotlinking.

Control which sites can embed or link to your CDN content based on the HTTP `Referer` header.

## Modes

* **Allow by default** — every referrer can fetch content; list domains to block.
* **Deny by default** — only domains in your allowlist can fetch content.

Add allowed or blocked domains under **Specify Domain(s)**.

## When to use this

* Stop other sites from hotlinking your images, videos, or downloads.
* Pin your video player to a known set of partner sites.

<Warning>
  The `Referer` header is sent by the client and can be spoofed or stripped. For high-value content, combine referrer rules with [Token Authentication](/docs/cdn/distributions/access-rules/token-authentication).
