• Rails routes matching query parameters

  - by Harry Wood

  Rails routes are great for matching RESTful style '/' separated bits of a URL, but can I match query parameters in a map.connect config. I want different controllers/actions to be invoked depending on the presence of a parameter after the '?'.
