File requested for comparison - also colleagues have submitted a request to also include Proxy Server functionality when the Private URL for IBM Cloud is used example below

def send_command(conn, command, method="GET", action=None, printResult=True): url = conn.base_url + command

    conn.setopt(pycurl.URL, url.encode("ascii"))
    conn.setopt(pycurl.PROXY, "http://192.168.150.4:3128")

    web_buffer = io.BytesIO()
