title: Valid JSON in Response
body: <p>I am working on a client and server application and came across an interesting problem.  We are creating a restful API and communicating to the clients with JSON responses.  When doing a DELETE, we are returning a 200 OK with a blank response.  Our clients are getting the 200 OK, but failing on parsing the JSON.</p>
  
  <p>We completely understand the failed parse (there is nothing to parse), but we had a bigger question.  Is sending a blank response valid JSON, or should we be returning <code>{}</code> or something to that effect?  Thanks.</p>
