# 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.
#
# This can be done by setting a `Referrer Policy` which
# whitelists trusted sources of content for your website.
#
# To check your referrer policy, you can use an online service
# such as: https://securityheaders.io/.
