HTTP Headers WordPress Plugin – Referrer-Policy

The HTTP Headers plugin can set a referrer-policy header to control what information is sent through the <code>referer</code> header with URI requests. This prevents URLs with sensitive information from showing up in web analytics software logs. For example, clicking links on a password reset page could send user credentials within the referrer.

Below we cover adding Referrer-Policy in WordPress with the HTTP Headers plugin.
