 * What exactly does Cache age control? Is it the time interval after which minifications
   are rebuilt, even if the original files have not changed?
    In that case, isn’t
   it better to detect modification automatically and only rebuild the minified 
   files in that case?

 * Cache age is used for client side only. When a minified file is served, the browser
   needs to know how long it should cache such file, and when the cache is expired
   browser will request it again, and that minified file is only rebuilt if original
   file has changed.
