title: what is the request object in browsersync middleware: function(req, res, next())
body: <p>Browsersync mentions the following. </p>
  
  <p>Does anyone know what are the properties of the request object ? e.g. How can I get the Host property of the request ?  </p>
  
  <pre><code> middleware: function (req, res, next) {
       //the following prints undefined - where can we learn about res, req and next()
       console.log(res.getHeader('Host'));
   }
  </code></pre>
