To clarify: the hash for the sensitive resource can be salted, making the hash unique and avoiding de-duplication. For non-sensitive resources, eg jquery.js, we can use an unsalted hash and get de-duplication.

Another benefit of identify resources by their hash is that we don't need to request them from a specific host. Instead, you can get them from any CDN that has a matching resource.
