I feel like empty isn't quite descriptive enough. An enum (though that's kind of
annoying to plumb from core -> web -> content) or a name like emptyResponseBody
might help.

I changed the chromium-side to use the name document_is_empty. Is the
blink-styled equivalent OK?

[dcheng, 2015/07/13 21:23:22]

Yes, that seems better.
