//this section enables you to use some controllers $route['admin/(:any)'] = "admin/$1"; $route['contact/(:any)'] = "contact/$1"; $route['auth/(:any)'] = "auth/$1"; $route['testimonials/(:any)'] = "testimonials/$1"; //else everything in url will handle by this pro controller's index function $route['(:any)'] = "pro/index";
