title: Does AFNetworking have backgrounding support?
body: <p>I'm in the process of investigating <code>AFNetworking</code> as a replacement for <code>ASIHTTPRequest</code>, and notice a complete lack of information on whether it supports background downloads/uploads.</p>
  
  <p>With an <code>ASIHTTPReqeust</code> object, all you have to do is call <code>[request setShouldContinueWhenAppEntersBackground:YES]</code> and the request will continue in the background. Is there any support for this in <code>AFNetworking</code>?</p>
