like this: www.xxx.com/aa/bb => www.xxx.com/aa/bb.html
@panjilekenan
the only way i know (till now) how to solve this, is to use costum routes: https://docs.phalcon.io/en/latest/reference/routing.html#usage-examples
example: blog.dev/backend/dashboard.html
$router->add("/backend/:controller\.html", array( 'module' => 'backend', 'controller' => 1, 'file' => 2 ));
