   # - HSTS tells a browser that the website should only be accessed through
   # - a secure connection. The HSTS header will be remembered by a standard
   # compliant browser for max-age seconds.
   # -
   # - Remember this settings for 1/2 year
   # -
   #Header add Strict-Transport-Security "max-age=15768000"
   Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"

   # - Referrer-Policy
   # -
   # - See: https://scotthelme.co.uk/a-new-security-header-referrer-policy/
   # -      https://www.w3.org/TR/referrer-policy/
   # -
   # - Referrer Policy is a new header that allows a site to control how
   # - much information the browser includes with navigations away from
   # - a document and should be set by all sites.
   # -
   # - The HTTP referer (originally a misspelling of referrer[1]) is an HTTP header
   # - field that identifies the address of the webpage (i.e. the URI or IRI) that
   # - linked to the resource being requested. By checking the referrer, the new
   # - webpage can see where the request originated.
   # -
   # - For a complete list and explanation of values, see urls above
   # -
   # - Example: "no-referrer-when-downgrade"
   # -          The browser will not send the referrer header when navigating
   # -          from HTTPS to HTTP, but will always send the full URL in the
   # -          referrer header when navigating from HTTP to any origin. It
   # -          doesn't matter whether the source and destination are the same
   # -          site or not, only the scheme.
   # -
   Header always set Referrer-Policy "strict-origin-when-cross-origin"
