[html5] Offline apps

[Martin Gainty]

# NETWORK Resources are pages that require the user to be online.
NETWORK:
login.php
/myapi
http://api.twitter.com

#FALLBACK when resource on left is offline serve pages on right 
# static.html will be served if main.py is inaccessible
# offline.jpg will be served in place of all images in images/large/
# offline.html will be served in place of all other .html files
FALLBACK:
/main.py /static.html
images/large/ images/offline.jpg
*.html /offline.html

i agree which caching to use can be very confusing

> I'm trying to figure out a way to make my app work offline. The app is

> of html, and the main page, which contains the list of pages. You can
> think of it as a catalog of pages.

> offline cache (the name of which is confusing), seems to interfere
> when the user is actually online. The result is, that page (the
> homepage of the application) comes from cache, and not from the
> server, and the user doesn't see the data he should be seeing, but
> sees the old cached version.

> complexity. I hope I'm missing the point (I'm new on this, I very well
> might be) and cache manifest can be used so that it starts making
> sense to me :) But now I don't quite understand how to use it right.
