what is the lifetime of ActionController, etc?

I realize that I don't know what causes an ActionController to be created and destroyed. As a specific example, consider:

  class UsersController < ApplicationController

    def myState       @myState ||= Object.new     end

    def show       ...     end end

Is there one ActionController created per user session? Will myState persist across GET and POST calls? Is the lifetime different in developer mode versus production mode?

To generalize the question: Are there any good references on the lifetime of various RoR objects in a running server?

No - one per request.
