These categories of loading apply consistently regardless of context. They interpret URLs globally. data: and blob: are specific URL schemes, and not especially different in this regard, though it is true they can be loaded without I/O.

These categories are content-specific. App cache and web archives can redefine the meaning of a URL and substitute an alternate resource, but this only applies to a particular page load.

I am not sure if the line drawing intentionally reflects this distinction, but I think it is a reasonable line to draw. 

It might make sense to change where the line is drawn. I am curious what people more involved in the networking code think.
