title: Rack space cloud files - download a file in a private container using PHP SDK
body: <p>I would like to download a private file (a file in a private container) from rackspace cloud files just using the api.</p>
  
  <p>I think it's possible to create a temporary hash/key, then redirect my logged user to an URL with this hash.</p>
  
  <p>Is it possible?</p>
  
  <p>How could I achieve this using the PHP SDK?</p>
  
  <p>Best regards!</p>
