title: Angular - wait on routing
body: <p>I have an app, that in it's "run" has an async http request.</p>
  
  <p>The request is to validate the user and his permissions.</p>
  
  <p>If I remove the async: true, it sends the request, but the router also fires, loading the template and initiating the controller.</p>
  
  <p>Is there a way to tell the router to 'wait', and fire it manually when I am ready?
  I don't want the controller to load into memory, because I don't know if this user has access to that module, and that module uses some global variables of the rootscope, loaded after the ajax response. </p>
