Feature-Policy:geolocation

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The HTTP Feature-Policy header geolocation directive controls whether the current document is allowed to use the Geolocation Interface. When this policy is enabled, calls to getCurrentPosition() and watchPosition() will cause those functions' callbacks to be invoked with a PositionError code of PERMISSION_DENIED.

By default, the Geolocation API can be used within top-level documents and their same-origin child frames. This directive allows or prevents cross-origin frames from accessing geolocation. This includes same-origin frames.

Syntax

Feature-Policy: geolocation <allowlist>;
<allowlist>

The allowlist is a list of origins that takes one of the following values:

  • *: The feature is allowed by default in top-level browsing contexts and all nested browsing contexts (iframes). 
  • 'self': (Default) The feature is allowed by default in top-level browsing contexts and in nested browsing contexts (iframes) in the same domain. The feature is not allowed in cross-origin documents in nested browsing contexts.
  • 'none': The feature is disabled in top-level and nested browsing contexts.
  • <origin(s)>: The feature is allowed for specific origins (for example, https://example.com). Origins should be separated by a space.

The values * (enable for all origins) or 'none' (disable for all origins) may only be used alone, while 'self' may be used with one or more origins.

The default value is 'self'.

Examples

General example

SecureCorp Inc. wants to disable the Geolocation API within all browsing contexts except for its own origin and those whose origin is https://example.com. It can do so by delivering the following HTTP response header to define a feature policy:

Feature-Policy: geolocation 'self' https://example.com

With an <iframe> element

FastCorp Inc. wants to disable geolocation for all cross-origin child frames, except for a specific <iframe>. It can do so by delivering the following HTTP response header to define a feature policy:

Feature-Policy: geolocation 'self'

Then include an allow attribute on the <iframe> element:

<iframe src="https://other.com/map" allow="geolocation"></iframe>

iframe attributes can selectively enable features in certain frames, and not in others, even if those frames contain documents from the same origin.
