{{HTMLSidebar}} 

The referrer value for the name attribute of the {{htmlelement("meta")}}  element controls the HTTP {{httpheader("Referer")}}  header of requests sent from the document. If specified, you define the referrer using a content attribute in the <meta> element as a keyword value.

For example, the following <meta> element sends the {{glossary("origin")}}  of the document as the referrer:

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

[!WARNING] Dynamically inserting <meta name="referrer"> (with {{domxref("Document.write", "document.write()")}}  or {{domxref("Node.appendChild", "appendChild()")}} ) makes the referrer behavior unpredictable. When several conflicting policies are defined, the no-referrer policy is applied.

Usage notes

A <meta name="referrer"> element has the following additional attributes:

• content
  • : Sets the document referrer. You must define this attribute. Accepts one of the following values:
    • no-referrer
      • : Does not send an HTTP Referer header.
    • origin
      • : Sends the origin of the document.
    • no-referrer-when-downgrade
      • : Sends the full URL when the destination is at least as secure as the current page (HTTP(S)→HTTPS), but sends no referrer when it’s less secure (HTTPS→HTTP). This is the default behavior.
    • origin-when-cross-origin
      • : Sends the full URL (stripped of parameters) for same-origin requests, but only sends the origin for other cases.
    • same-origin
      • : Sends the full URL (stripped of parameters) for same-origin requests. Cross-origin requests will contain no referrer header.
    • strict-origin
      • : Sends the origin when the destination is at least as secure as the current page (HTTP(S)→HTTPS), but sends no referrer when it’s less secure (HTTPS→HTTP).
    • strict-origin-when-cross-origin
      • : Sends the full URL (stripped of parameters) for same-origin requests. Sends the origin when the destination is at least as secure as the current page (HTTP(S)→HTTPS). Otherwise, sends no referrer.
    • unsafe-URL
      • : Sends the full URL (stripped of parameters) for same-origin or cross-origin requests.

Examples

Removing a referrer from requests

The following <meta> element specifies that the document shouldn’t send a Referer header with HTTP requests from the document:

<meta name="referrer" content="no-referrer" />
