title: Laravel 5 redirect to home page if attempting to go to login screen
body: <p>I have a login screen which is the base url (www.mysite.com/).</p>
  
  <p>When a user logs in they are redirected to their home page (/home).</p>
  
  <p>But the can still get back to the login page if they go to the root.</p>
  
  <p>How do I make it so logged in users are sent back to their home page if they are logged in (if they are not, of course they see the login page)?</p>
