title: Laravel flash or session messages not expiring [ not maintained Updated ]
body: <p><strong>Updated after some research</strong><br>
  After some research I conclude that, my sessions are not maintained until I save them explicitly, <strong>below code works well, but WHY????</strong> <a href="https://laravel.io/forum/09-07-2016-session-not-saving-laravel-53" rel="nofollow noreferrer">Ref here</a></p>
  
  <pre><code>Session::put('lets_test', 2);
  Session::save();
  </code></pre>
  
  <p><strong>Old Question</strong><br>
  I'm new to laravel 5.3, and stuck at a problem. My Laravel Session or Flash messages are not expiring they display each time page is reloaded, until I use <code>Session::flush()</code> Below is my controller code</p>
  
  <pre><code>&lt;?php
  
  namespace App\Http\Controllers;
  
  
  use Session;
  use Auth;
  use Illuminate\Http\Request;
  use App\User;
  use App\Hospital;
  use App\Wpr;
  use Helper;
  
  class OperatorController extends Controller
  {
      public $user_detail;
  
      public function __construct()
      {
          $this-&gt;middleware('auth');
          $this-&gt;middleware('operator');
      }
      public function store (Request $request){ //Form is being submitted here
          //My logic here
          Session::flash('user_message', 'Thank You');
          return redirect('/operator/wpr');
      }
  }
  </code></pre>
  
  <p>I've also used <code>Session::set('user_message', 4);</code> 
  and blade view</p>
  
  <pre><code>@if(Session::has('user_message'))
      &lt;div class="message  animated tada"&gt;
          {{ Session::get('user_message') }}
      &lt;/div&gt;
  @endif
  </code></pre>
  
  <p>I've tried with <code>Session::forget('user_message')</code> but no luck.
  Updating my post after some research. I've got somewhat close to my problem by <a href="https://stackoverflow.com/questions/29346743/laravel-5-session-doesnt-work" title="reading this on stack">reading this post on stack</a> because this question is exactly same to my problem but unfortunately it still persists, I've changed my session storage from file to database (in case file permissions to storage directory). What might be other possibilities?</p>
  
  <p>Please help, thanks in advance.</p>
