The thread on caching got me thinking about ServiceWorker and how it might interact with SRI. One of the goals of SW is to transparently provide alternate resolutions to a fetch, perhaps based on online/offline connectivity or connection characteristics. e.g. load HD images over Wifi, low-res ones over metered 3G, and show a styled placeholder when offline. It seems like it might be useful then to allow supplying multiple integrity attributes to accommodate this behavior. e.g. "this video should have hash ni://abc (actual content) or ni://xyz (you're offline placeholder content). Thoughts? -BradReceived on Monday, 6 October 2014 17:35:52 UTC
