[Catalyst] Create a session after login only?

[Octavian Rasnita]

Hi,

I use the following Catalyst plugins in my app:
Session, Session::Store::File, Session::State::Cookie
Authentication, Authorization::Roles

The problem is that on each request of the main page, the app creates 2 
session files before even logging in.

Is it possible to make it generate session files only for the logged-in 
users?

Thanks.
