Okay. So currently the mix of the Origin specification and the HTML
specification suggests you either do "Origin: /origin/" or "Origin:
null". However WebKit seems to do "Origin: /origin/" or no header at
all (for the "privacy-sensitive" cases). Ian also mentioned that we
can not just put the Origin header into every outgoing request as that
breaks the interwebs (per research you did for Chrome I believe?).

What do you think we should end up requiring?
