'Convenience method to synchronously fetch a URL.
The given path will be appended to the local server\'s host and
port.  Any additional kwargs will be passed directly to
`.AsyncHTTPClient.fetch` (and so could be used to pass
``method="POST"``, ``body="..."``, etc).
If the path begins with http:// or https://, it will be treated as a
full URL and will be fetched as-is.'

    if path.lower().startswith(('http://', 'https://')):
        self.http_client.fetch(path, self.stop, **kwargs)
    else:
        self.http_client.fetch(self.get_url(path), self.stop, **kwargs)
    return self.wait()
