* An implementation of a

* request strategy.
*
* Resources are requested from both the cache and the network in parallel.
* The strategy will respond with the cached version if available, otherwise
* wait for the network response. The cache is updated with the network response
* with each successful request.
*
* By default, this strategy will cache responses with a 200 status code as
* well as [opaque responses]{@link https://developers.google.com/web/tools/workbox/guides/handle-third-party-requests}.
* Opaque responses are cross-origin requests where the response doesn't
* support [CORS]{@link https://enable-cors.org/}.
*
* If the network request fails, and there is no cache match, this will throw
* a `WorkboxError` exception.
