    # The OAuth signature uses the endpoint URL as part of the request to be
    # hashed. By default, the oauthlib library rejects any URLs that do not
    # use HTTPS. We turn this behavior off in order to allow edX to run without
    # SSL in development mode. When the platform is deployed and running with
    # SSL enabled, the URL passed to the signature verifier must start with
    # 'https', otherwise the message signature would not match the one generated
    # on the platform.
