Question about routing in Kohana?

Question

Kohana

Good for all! There is a task for routing Kokhan, I want to make such a
route "site.ru/city/type of institution/name/ - site.ru/london/pub/gunandroses"
and if the request goes to "site.ru/city" then it pulls out a list establishment by this city,
and if the request goes to "site.ru/city/type of establishment" then it pulls out a list of establishments by city and, upon request, the type of establishment
How to do this?
I'm thinking of making the city through cookies, or a third-level domain, which is better?

Route::set('default', '((/<city>)(/<type>)(/<name>))')
  ->defaults(array(
    'controller' => 'places',
    'action'     => 'search',
  ));

Answer 1

Route - site.ru / city / type of institution / name

Route::set('place', '<city>(/<type>)(/<name>)')
  ->defaults(array(
    'controller' => 'places', 
    'action'     => 'place',
  ));
