title: REST: HTTP headers or request parameters
body: <p>I've been putting in some research around REST. I noticed that the <a href="http://docs.amazonwebservices.com/AmazonS3/2006-03-01/API/" rel="noreferrer">Amazon S3</a> API uses mainly http headers for their REST interface. This was a surprise to me, since I assumed that the interface would work mainly off request parameters.</p>
  
  <p>My question is this: Should I develop my REST interface using mainly http headers, or should I be using request parameters? </p>
