readline is fun

rl.on('line', function (line) {
  if (line.match(/rel="stylesheet"/)) {
    var newLine = line.replace(/(.*)/, '$1<script> </script>');
    ws.write(newLine + '\n', 'utf8', function () {
      console.log(1)
    });
  } else {
    ws.write(line + '\n', 'utf8', function () {
      console.log(2)
    });
  }
});
