[html5] Offline apps

[Oliver Schmidt]

Hi Ilkka,

a  few  months  ago,  I've  been experimenting with the offline cache.
I  think  there  is  one easy way to achieve what you want to: If your
content  got  updated,  you should update the cache manifest (version)
which  in  turn forces browsers to update their caches. Please correct
me if I'm wrong...

Oliver
