title: batch http requests
body: <p>Does anyone know a standard way to batch http requests? 
  Meaning - sending multiple http atomic requests in one round trip?</p>
  
  <p>We need such mechanism in our REST API implementation for performance reasons. This kind of mechanism can reduce dramatically the number of round trips that the client needs to perform to consume the API.</p>
  
  <p>Thanks in advance,</p>
