I would be fine with that, but it would be a violation of HTTP semantics. If you can get the HTTP working group to change their requirements, I'd be very happy to change the spec here. > * Its not clear that resources add()ed around update initiation time > will make their way to a new cache that results from the update.

A network fetch can take an indeterminate amount of time, so it's not clear to me that this would be that useful. There's hasItem() method if the application needs to know if the add has succeeded yet. add() is idempotent, too, so if the app really wants to make sure something is in the cache it could just keep trying to add it or something... > * Pseudo code omission (i think): I don't see where the pseudo code > inserts new master entries or informs already running update of newly > discovered master entry. It's done in the application cache selection algorithm, and then as part of step 1 of the application cache update process. I've hyperlinked one use of the word "master" that wasn't hyperlinked before, which might help. I agree that this text isn't uber-clear. > * Towards the end of an update, 'candidates' are not associated with the > new cache in the upgrade attempt case. The differences between the cache > attempt vs upgrade attempt seems odd. In the upgrade case, they're already associated. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
