title: Laravel redirect back to original destination after login
body: <p>This seems like a pretty basic flow, and <code>Laravel</code> has so many nice solutions for basic things, I feel like I'm missing something.</p>
  
  <p>A user clicks a link that requires authentication.  Laravel's <em>auth</em> filter kicks in and routes them to a login page.  User logs in, then goes to the original page they were trying to get to before the 'auth' filter kicked in.</p>
  
  <p>Is there a good way to know what page they were trying to get to originally?  Since Laravel is the one intercepting the request, I didn't know if it keeps track somewhere for easy routing after the user logs in.</p>
  
  <p>If not, I'd be curious to hear how some of you have implemented this manually.</p>
