You should be able to simply update the manifest file dynamically on the
server side, whenever your page or application is updated.
The smallest change should trigger a re-download, which means that even
changing a comment in the manifest file would make UAs fetch the resources
It would be nice if there was a way to trigger such re-downloads
individually, as all files might not be updated. I'm sure some sites or
applications would find this useful.
It has been suggested to simply include a version number, or whatever, in a
comment, and increment that when your page/app gets updated, but basically
anything would work.
You may however also want to consider how many requests this actually saves
you, compared to using etag and cache headers.
