title: AEM - get current UserId
body: <p>I have some code in my AEM world that does a form ajax call to a restlet service.  What I would like to know is what the code is to get the current logged in UserId?  The page has session=false.  </p>
  
  <p>Does AEM have a cookie I can pull against?
  In the form I have a hidden field named cq_csrf_token but I did not see it matching up with anything from CRXDE.</p>
  
  <p>If you know it would be cool to hear your input. </p>
