Safari clears the cache for everything except the particular win-
dow that you have visible, so when you refresh, it's still got the
cache manifest included. This goes for the iPhone in particular.
For Chrome, you can navigate to chrome://appcache-internals/
where you can specifically remove a cache for a URL.
For Firefox, you need to open Preferences, go to the Advanced
tab, and select the Network tab. From there you can clear indi-
vidual domains' cache.
For Opera, open Preferences, navigate to Advanced, and select
Storage. From there you can individually remove a URL's storage.
Although they call this section persistent storage (suggesting
that it refers to localStorage and sessionStorage ) there appear
to be extra URL entries with data stored, often in the form of
the domain with a hash at the end, for instance html5demos.
com/$7b8e3c7f. It's unclear exactly what this is (clearing this last
one empties neither the AppCache nor the localStorage ) but to
be on the safe side I'd recommend removing both.
In the past, websites often failed to work when users weren't
connected to the Internet. Browsers are now beginning to sup-
port offline use, coupled with the ability to detect whether or not
a browser is currently online or offline (with a few workarounds).
