title: What is the difference between SESSION_DRIVER=file and SESSION_DRIVER=redis in env laravel?
body: <p>I use laravel 5.3</p>
  
  <p>In my localhost, the env like this :</p>
  
  <pre><code>CACHE_DRIVER=redis
  SESSION_DRIVER=file
  QUEUE_DRIVER=redis
  
  REDIS_HOST=127.0.0.1
  REDIS_PASSWORD=null
  REDIS_PORT=6379
  </code></pre>
  
  <p>In my production, the env like this :</p>
  
  <pre><code>CACHE_DRIVER=redis
  SESSION_DRIVER=redis
  QUEUE_DRIVER=redis
  
  REDIS_HOST=127.0.0.1
  REDIS_PASSWORD=null
  REDIS_PORT=6379
  </code></pre>
  
  <p>Almost all the same, just SESSION_DRIVER different</p>
  
  <p>What is the difference between SESSION_DRIVER=file and SESSION_DRIVER=redis?</p>
