 # ----------------------------------------------------------------------
 
-# A web application uses HTTPS and a URL-based session identifier.
-# The web application might wish to link to HTTPS resources on other web
-# sites without leaking the user's session identifier in the URL.
+# Set a strict Referrer Policy to mitigate information leakage.
 #
-# This can be done by setting a `Referrer Policy` which whitelists trusted
-# sources of content for your website.
+# (1) The `Referrer-Policy` header is included in responses for resources
+#     that are able to request (or navigate to) other resources.
 #
-# To check your referrer policy, you can use an online service such as:
-# https://securityheaders.io/.
+#     This includes the commonly used resource types:
+#     HTML, CSS, XML/SVG, PDF documents, scripts and workers.
+#
+# To prevent referrer leakage entirely, specify the `no-referrer` value
+# instead. Note that the effect could impact analytics metrics negatively.
