title: How to correctly redirect after doing POST in Laravel?
body: <p>I have multiple routes with comments and when I click reply I get redirected to a route where I can post a reply to a comment. How can I correctly store the route from where I came and then redirect back to it after posting the reply? </p>
  
  <p>I considered passing the URL::previous as a param and storing it into a hidden input, but if the page gets refreshed by the user it gets empty. Another way might be store in the session, but then I don't know how to reliably expire it... </p>
