HTTPS request through Proximo returns what appears to be encoded

I am using proximo on a heroku hosting to proxy my requests.

When I send a proximo request through the http I am able to receive data but it seems to be encrypted. If I use the https module I get a socket hang up error.

app.get('/', function (req, res) {
    // This is stuff for proximo
    var proxy = url.parse("http://url-of-my-proxy.com");
    var headers, key, options, val, _ref;
    headers = {
        "Proxy-Authorization": "Basic " + (new Buffer(proxy.auth).toString("base64")),
        "Host": "www.googleapis.com"
    };
    delete req.headers.host;
    _ref = req.headers;
    for (key in _ref) {
      val = _ref[key];
      headers[key] = val;
    }
    // This is the actual request
    options = {
        hostname: proxy.hostname,
        port : proxy.port || 80,
        path : "https://www.googleapis.com/customsearch/v1?key=myKeycx=myKey&q=" + q, // I need this to be in https, else google returns an error
        headers : headers
    };
    var req = http.get(options, function (response) {
        response.setEncoding('utf8');
        response.on('data', function (data) {
            console.log("Answer : ", data); // Here I see only unreadable characters like the answer is encoded

        });
    })
    req.on("error", function (err) {
        callback(err, false);
    });
}

So I assume that what I receive is pure https data and it needs to be decrypted. But I can't find how.

My initial result was: <Buffer 1f 8b 08 00 [...] 83 ...>

Then I read that I need to use the utf8 encoding and got: �H�(er : ��1�0�r�:BHP� �Kv�Le������h��UE�7¹#I�yE�R� (G�1+'~��rr\�,.�|�F�F�sԄ��h�vw!�b˲��]�$���?�������F�

Is there something I am missing to get the result of my request here?

Edit:

I now know that the content was zipped, so with a little modification I was able to get the data:

var zlib = require('zlib');
var req = https.get(options, function (response) {
    response.pipe(zlib.createGunzip()).pipe(process.stdout);
});

Piping the answer to the console. But I get the google error saying that my request needs to be https.

So the problem is still there: If I send an https request I just get no answer for Proximo. Is it that they don't support https or is there any other way?
