IMO, this modification is needed?

    def do_OPTIONS(self):
        self.send_response(200)
        self.send_cors_all()
        self.send_header("Access-Control-Allow-Headers", "X-Requested-With, Content-type")
        self.end_headers()

I just tried only with google chrome, though.

OK cool, I will add to send_cors_all ;)

[nrryuya]

In OPTIONS it should response I think? like

 def do_OPTIONS(self):
        self.send_response(200)
        self.send_cors_all()
        self.end_headers()

Is it complaining about not having a response code?

[nrryuya]

Yes, when I did a experiment without response code with Chrome, ERR_INVALID_HTTP_RESPONSE occurs.
(Sorry for not explaining enough)
