Secure context
This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The manifest attribute of <html> element specifies a URL of a application cache manifest that is downloaded in the early stages of page load.

Note: manifest-based caching mechanism has been deprecated. Use service workers instead.

The manifest attribute has only effect during early stages of page load, thus changing it via regular DOM interfaces has no effect, Window.applicationCache interface instead.
