        If the client is expecting a 100 Continue response, we must
        respond with either a 100 Continue or a final response before
        waiting for the request body. The default is to always respond
        with a 100 Continue. You can behave differently (for example,
        reject unauthorized requests) by overriding this method.

        This method should either return True (possibly after sending
        a 100 Continue response) or send an error response and return
        False.
