I realize that I don't know what causes an ActionController to be
created and destroyed. As a specific example, consider:
class UsersController < ApplicationController
@myState ||= Object.new
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?
