/*! 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.
