title: How Symfony routing works
body: <p>I am a beginner for Symfony and following the Symfony documentation and it has <a href="http://symfony.com/doc/current/page_creation.html" rel="nofollow">a create page tutorial</a> 
  and after creating this this when I test this using the browser,</p>
  
  <p>I can access it using the following URLs</p>
  
  <p>localhost:8000/lucky/number and</p>
  
  <p>localhost:8000/app_dev.php/lucky/number</p>
  
  <p>but when I try to access it using the usual way like</p>
  
  <p>localhost/appname/lucky/number </p>
  
  <p>it gives 404 and I use Ubuntu with Apache2 localhost so I need to know the idea behind this Symfony3 routing and why I cannot access the page using usual <strong>localhost/cmstest/lucky/number</strong></p>
  
  <p>Thanks</p>
