Questions tagged [application-cache]

The Application Cache (or AppCache), part of HTML5, allows a developer to specify which files the web browser should cache and make available to offline users. Your app will load and work correctly, even if the user presses the refresh button while they're offline.

Application Cache is an obsolete part of HTML5:

Do not use it in old or new projects. Pages or Web apps using it may break at any time. It's in the process of being removed from the Web platform. Use Service Workers instead.
