It's a pity that there isn't currently a way to leverage cached resources with different URLs for the same content. In fact this would not be hard: if you could indicate, with the resource URL, the hash of the resource content, the browser could just use the resource with that hash if it has it in cache (no matter from which URL), and otherwise retrieve it, check the hash, and add it to the cache.
