# Ensure that Rails sets appropriate caching headers on static assets if
    # Rails is serving static assets in production e.g. on Heroku
    #
    # Overview of Cache-control values:
    #
    #     max-age=<seconds>
    #         The maximum amount of time a resource is considered fresh.
    #
    #     s-maxage=<seconds>
    #         Overrides max-age or the Expires header, but only for shared
    #         caches (e.g., proxies). Ignored by private caches.
    #
    #     More info: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control
    #
    # Our Cache-Control header:
    #
    # * It tells all caches (both proxies like Cloudflare and the users web
    #   browser) that the asset can be cached.
    # * It tells shared caches (e.g. Cloudflare) that they can cache it for 365 days
    # * It tells browsers that they should cache for 365 days
    #
    # Cloudflare will respect s-maxage if it is set so change that value if you
    # want Cloudflare to cache differently than then browser.
