     /*! Cache Header Notes
      *
      *  # Cache-Control
      *  [public | private] Cacheable when public, otherwise the client is responsible for caching.
      *  [no-cache( \w+)?]  When no fields are specified, the whole thing must revalidate everytime,
      *                     otherwise cache it except specified fields.
      *  [no-store] 				 Ignore caching and pipe into output.
      *  [max-age=\d+] 		 Seconds before this cache is meant to expire, this overrides Expires header.
      *  [s-maxage=\d+] 		 Overrides max-age and Expires header, behaves just like max-age.
      *                 	   (This is for CDN and we are using it.)
      *  [must-revalidate]  Tells those CDNs which are intended to serve stale contents to revalidate every time.
      *  [proxy-revalidate] Like the "s-" version of max-age, a "must-revalidate" override only for CDN.
      *  [no-transform]     Some CDNs will optimize images and other formats, this "opt-out" of it.
      *
      *  # Expires
      *  RFC timestamp for an absolute cache expiration, overridden by Cache-Control header.
      *
      *  # ETag
      *  Hash of anything, weak ETags is not supported at this moment.
      *
      *  # vary
      *  Too much fun inside and we are too serious about caching, ignore this.
      *
      *  # pragma
      *  This guy is too old to recognize.
      *  [no-cache] Only this is known nowadays and is already succeed by Cache-Control: no-cache.
