onobsolete event
Event handler provided to indicate that the application cache cannot be found.
Syntax
Event handler parameters
handler [in]
Type: FunctionEvent handler
Remarks
If the manifest file can't be found, the cache is considered to be deleted.
If there is more than one event, the obsolete event will be the last one in the sequence.
Alternatively, you could use an anonymous delegate function such as
object.onobsolete = function (e) { … }
where e is the cached event.
