title: rest api expected response for GET
body: <p>I am working on making a rest api and I have a question about what is typically returned from a get with no match.  For instance if my resource is "users" and I make an api call with</p>
  
  <p>http method: GET
  url: api.mysite.com/users/123</p>
  
  <p>If '123' exists I will return a http code of 200 with the details of the user in the response body.  My question is; what http code should I return, and what should I put in the response body if there is no user with the id of 123?</p>
  
  <p>Should I just return a code of 200 and an empty body?</p>
