Middleware snippet from: Can't get rid of header X-Powered-By:Express

function customHeaders( req, res, next ){
  // Switch off the default 'X-Powered-By: Express' header
  app.disable( 'x-powered-by' );

  // OR set your own header here
  res.setHeader( 'X-Powered-By', 'Awesome App v0.0.1' );

  // .. other headers here

  next();
}

app.use( customHeaders );
