  maxAge: '1y',
  setHeaders: function (res, path) {
    if (mime.lookup(path) === 'text/html') {
      res.setHeader('Cache-Control', 'public, max-age=0')
    }
  }
}))

app.use(function (req, res, next) {
  console.log(req.url);
  if (req.url !== '/app/index.html') {
    res.header('Cache-Control', 'public, max-age=600s')
