This will probably work for most of the platforms, except the one that uses
multi-process architecture. How do we handle the case that a page is trying
to access a blob URL that is created in another process (assume the
accessing page is in the same security domain)? I think for the platform,
like Chromium, we can choose to delegate to the host to do the right job,
while all other platforms will share the same handling logic defined at a
In addition, we might need to hook up additional logic if we want to support
using it in the shared worker process.
