title: How to set cookies in ApplicationController?
body: <p>I need to set cookies in my ApplicationController but I'm not sure how. I've tried using cookies - nothing, using ActionController::Cookies - nothing.
  I don't need anything more then setting and getting cookies but what I do need is to set them in <strong>ApplicationController</strong>.</p>
  
  <p>EDIT:</p>
  
  <p>Found the answer: <code>request.cookies['help'] = 'yes'</code></p>
