Details

Recently I tried making a simple pre-cache service worker with a variety of cross-origin resources.  This failed to install due to NetworkError rejections.  The console message, however, was not particularly helpful.  I had no idea if it was due to MIX violations, CORS header failures, or something else.

The one helpful message I did get was when I got an opaque response in cache.addAll().  I believe it told me that the status was 0 instead of 2xx.
