title: Is it possible to call the function in controller based on certain page without frontend plugin?
body: <p>When i open a site in Typo3, i want the site to call a certain controller for that site and then output the layout. Preferably with the same name like "TestController.php" for the controller and "Test.html" for the layout.</p>
  
  <p>I know that it's possible with FrontEnd plugin. The problem with FrontEnd plugin is that i need to add the plugin to the site that i want. What i really want is to write an extension, that once installed will work on all sites. </p>
  
  <p>Is it actually possible to do this in typo3? Maybe with some configuration files?</p>
