Experiments in HTML5 Appcache

Can't seem to get much joy out of navigator.onLine on Chrome or Firefox on Desktops.

However on Android, trigger Airplane mode quickly makes it change to a red border colour.

Demo site: http://demo2.webconverger.com

Test cache idea

Load large file in the background to play back later. Play it back by going offline and going to a random URL on the http://demo2.webconverger.com site to trigger fallback.

Chromium

Does not seem to want to download mvi_5948.ogg

Application Cache Error event: Resource fetch failed (-1) http://demo2.webconverger.com/mvi_5948.ogg

Is there a limit? Is 71M too large?

It's there and ready to download:

$ curl -I http://demo2.webconverger.com/mvi_5948.ogg

Firefox

Can't understand how to debug network in Firefox 10. Doesn't seem to download OGG in background as expected to. :(

Work around for triggering offline mode in Firefox is the "Work Offline" mode from the File menu.
