function query_parameters_to_url_init in Query Parameters To URL 7

Implements hook_init().

There are situations when we can't alter a link, like a submitted Views exposed filter, which sets the query parameters via a form, with the form action set to GET. In those cases we will do a redirect to the Clean URL, only the specified paths.
