Set HTTP Request Header 

Is there a way to set/add request header to the call?
I would need to add 'Cache-Control': "private, no-cache, no-store" .

``
function urlToPromise(url) {
  return new Promise(function(resolve, reject) {
    JSZipUtils.getBinaryContent(url, function(err, data) {
      if (err) {
        reject(err);
      } else {
        resolve(data);
      }
    });
  });
}
``
