url routing, friendly url

my route file has route['(:any)'] = “web/index/$1″ to bring URL friendly: localhost/my-slug-url, it works good (am using slugs from database), but my dashboard class does not work if I use the route['(:any)'] the problem is that how can I access the dashboard class “dashboard” (has functions add/remove/edit)

I want to make url : localhost/this-is-my-domain without using route ? the simple I can let you feel my issue is about … and even I can access other class and controller.
