title: Play Framework : Get session using session id
body: <p>I am using <a href="http://www.uploadify.com/" rel="nofollow">Uploadify</a> to handle mutli-file uploads in my Play app and I am trying to work out the best way to associate a user with an upload.</p>
  
  <p>Within uploadify, you are able to assign <a href="http://www.uploadify.com/documentation/options/scriptdata/" rel="nofollow">script data</a> which are key value pairs passed as parameters to the server. So my idea, on the most basic level, is that I would like to pass the <code>id</code> of the users current <code>session</code> back to the upload method and then use the <code>session id</code> to get the <code>session</code>.</p>
  
  <p><i><b>My question is:</b> does anybody know how to get a session using the session id?</i></p>
  
  <p>I understand that this is not the most secure way of doing this and I will be adding a few more complications along the way. However, if someone knows, or can think of, a better away to achive what I am trying to do then I welcome their input.</p>
