Rails3 parameters in routes

In Rails 2 I was able to specify extra parameters within a route, like this: map.login "login", :controller => "user_sessions", :action => "new", :tag_index => true The tag_index would be available in the controller via params[:tag_index].

I've searched to find a simular solution within Rails 3, but I'm still unable to find it. Does anybody know a solution?
