Avoids Application Cache


Application Cache, also known as AppCache, is deprecated.


Consider using the service worker Cache API instead.

To help migrate from AppCache to service workers, consider the sw-appcache-behavior library. This library generates a service-worker-based implementation of the behavior defined in an AppCache manifest.

See the URL Responds With a 200 When Offline audit reference for more resources on using service workers to make your site work offline.
