How can I go around having a single route that would internally be forwarded to a controller depending on some internal logic. I've looked into dynamic routes but it doesn't help since the route is shared, not dynamically created (ie "my/page")
In symfony I could do this
$this->forward('AppBundle:Something:fancy',$params) but I've been unable to do this in Drupal 8.
I also looked into middleware since it looked promising but I couldn't figure out a way of doing it either.
