title: Laravel 5 - session doesn't work
body: <p>Here's <code>config/session.php</code>:</p>
  
  <pre class="lang-php prettyprint-override"><code>return [
      'driver' =&gt; 'file',
      'files' =&gt; storage_path().'/framework/sessions',
  ];
  </code></pre>
  
  <p>My <code>storage/framework/sessions</code> have 755 permissions.</p>
  
  <p>When I put these 2 line in my controller</p>
  
  <pre class="lang-php prettyprint-override"><code>Session::set('aa', 'bb');
  dd(Session::get('aa'));
  </code></pre>
  
  <p>I receive expected <code>"bb"</code> output. But if I comment first line:</p>
  
  <pre class="lang-php prettyprint-override"><code>// Session::set('aa', 'bb');
  dd(Session::get('aa'));
  </code></pre>
  
  <p>and refresh page, I still expecting <code>"bb"</code> but getting <code>null</code>.</p>
  
  <p>Also, <code>storage/framework/sessions</code> is empty.</p>
  
  <p>What should I do to make Session working?</p>
