        path      : myUrl.path,
        agent     : false  // Create a new agent just for this one request
    };    

    var options = {...defaultOptions, ...options};

    return new Promise(async function(success, fail)
    {
        protocol.get(options, (res) => 
        {
            if (res.statusCode !== 200) {

            res.on('data', function(chunk) 
            {
