title: HTTP status code for 'Loading'
body: <p>A server receives a request, but decides that the request will take to long to process, so it responds with a site saying <em>Loading...</em>. The site will refresh itself until the client receives the response indicating that the (first) request has been completely processed.</p>
  
  <p>What's the most appropriate status code for this <em>Loading...</em> site?</p>
  
  <p>My guess is that it is <em>202 Accepted</em>.</p>
