Overview

This document describes a proposal the "referrer" metadata name. Using the referrer metadata attribute, a document can control the behavior if the Referer HTTP header attached to requests that originate from the document.

Specification

Keyword: referrer

The referrer metadata attribute can have one of four values:

  • never (Never include a Referer header.)
  • always (Always include a Referer header.)
  • origin (Use the document's origin in the Referer header.)
  • default (Use the user agent's default policy for whether to include a Referer header.)


Examples

This meta element instructs the user agent to omit the Referer header in all HTTP requests that originate from the document containing the element:

<meta name="referrer" content="never">

This meta element instructs the user agent to include the document's origin in the Referer header rather than the full URL of the document.

<meta name="referrer" content="origin">
