title: Why can some urls contain "fake" directories?
body: <p>Currently, I'm trying to set up updates for passes that are added to the Wallet app on iOS. </p>
  
  <p>One thing that is interesting is that having the url <code>https://example.com/index.php/var1/var2</code> still works and index.php is still run. Is there a reason why this url format works?</p>
