How to implement redirection for all requests (under certain conditions)?

Question

I want to configure something so that if the account in my application is disabled, I want all requests to be redirected to the message "disabled".

I installed this in my ApplicationController application:

class ApplicationController < ActionController::Base
  before_filter :check_account

  def check_account
    redirect_to :controller => "main", :action => "disabled" and return if !$account.active?
  end
end

Of course, this does not work, because it goes into an endless loop if the Account is inactive. I was hoping to use something like:

redirect_to :controller => "main", :action => "disabled" and return if !$account.active? && @controller.controller_name != "main" && @controller.action_name != "disabled"

but I noticed that in Rails v2.1 (what I use), @controller is now a controller, and this does not seem to work in ApplicationController.

What would be the best way to implement something like this?

If you don't override too much, then just put the if in the redirect filter

if action! = disabled redirection () end
