cache = window . applicationCache
(In a window.) Returns the ApplicationCache object that applies to the active
document (page 608) of that Window.
cache = self . applicationCache
(In a shared worker.) Returns the ApplicationCache object that applies to the
current shared worker.
cache . status
Returns the current status of the application cache, as given by the constants
defined below.
cache . update()
Invokes the application cache update process.
Throws an INVALID_ACCESS_ERR exception if there is no application cache to update.
cache . swapCache()
Switches to the most recent application cache, if there is a newer one. If there isn't,
throws an INVALID_ACCESS_ERR exception.
Objects implementing the ApplicationCache interface must also implement the EventTarget
interface.
There is a one-to-one mapping from cache hosts (page 662) to ApplicationCache objects. The
applicationCache attribute on Window objects must return the ApplicationCache object
associated with the Window object's active document (page 608). The applicationCache
attribute on SharedWorkerGlobalScope objects must return the ApplicationCache object
associated with the worker.
