Hi,

Does anyone know when exactly the “controller” objects are created in  
rails?  
when the http server starts? or when it is answering a http request? or  
…  
thanks you very much.

Sayoyo

The dispatcher will handle each request and a new controller  
is instantiated by the routing system when a route is recognized.

In ActionController::Dispatcher, you’ve got this method :

```
  def handle_request
    @controller = Routing::Routes.recognize(@request)
    @controller.process(@request, @response).out(@output)
  end

```
