1Test that a 404 response for manifest results in cache removal. 2 3Frame 1: Manifest is still available, so a new master resource is added to the cache. 4Frame 2: Manifest loading results in 404 response, so the cache group becomes obsolete, and an obsolete event is dispatched (because the document in frame was associated with a cache in the group). 5Frame 3: Manifest is still 404 - the document is never associated with a cache. 6Frame 4: Manifest is now available, so the document gets associated with a cache in a newly created group; the obsolete cache group is not affected. 7Should say SUCCESS: 8 9SUCCESS 10 11
