Rails - Feb 2011 - concurrent users.

If I have:

class ApplicationController < ActionController::Base
  protect_from_forgery
  before_filter RubyCAS::Filter
  before_filter :fetch_operator
  include SessionsHelper

  private

  def fetch_operator
    @operator ||= session[:cas_user] &&
Operator.find_by_uid(session[:cas_user])
    log_out if @operator.nil?
  end

end

@operator is available for all controllers of my application.
But If I run, for example, two instances of my application from
different locations.
In the first instance the user logs in as ''user1'', later from
another
location, another user logs in as ''user2'', then in @operator
now I
have ''user2''.
How can I do if my application is used by more than one user?

That shouldn''t happen - each request has its own controller instance,
so setting @operator to one value for one request should have no
effect on its value for another request.
