title: Session pull and/or flush does not remove session data
body: <p>I have this line of code in my login method </p>
  
  <pre><code>Session::put('msg','Welcome user');
  </code></pre>
  
  <p>And with a simple route a get through AJAX the value of that message and then delete it ( in theory ) (It's like a flash message):</p>
  
  <pre><code>public function getMessage( ){
  
      $msg = Session::pull('msg','');// tried this 
  
      Session::flush();// and/or this 
  
      return $msg;
  }
  </code></pre>
  
  <p>Still the message from session is not removed. I want it behave like a flash message . Why the value still persists if I used <code>Session::pull()</code> and\or <code>Session::flush()</code>?</p>
