You should not have relative url's in your view files (html-files). Check out some common MVC-like PHP frameworks like Laravel or Symfony. They all have methods which provides you the full qualified url for you vew-files like: http://domain.tld/controller/param/... instead of /cobntroller/..
Implementing this should solve your problem.
For example check out Laravel. It's very easy to understand and pretty flexible. There you have access to all your route with functions like Redirect::route('your-route-name'). The routing engine will then translate this into the full url!
EDIT: Just to be more precise, laravel is not a real mvc by definition. But in some parts it acts like a mvc.
Hope this helps
