cacheThe cache plugin uses the Cache API to save content in visitor’s browser for later use (when offline or when the website is down for whatever reason, for instance).
As a stashing plugin, it is handled in a special way by LibResilient:
cache returns a successful response, the cache plugin caches it for later use.cache succeeds, cache returns the cached response; afterwards, plugins configured after cache are run in the background to try retrieving a fresher response; if any of them succeeds, cache plugin caches it for later use.The cache plugin does not have any configuration options.
