  This document does NOT define the Cross-Origin-Embedder-Policy header.

  Cross-Origin Embedder Policy Editor's draft: https://mikewest.github.io/corpp/

  CacheStorage. The resources are generated from the ServiceWorker or from the

  network with the header Cross-Origin-Resource-Policy being one of:

    - 'same-origin'

    - 'cross-origin'
