Rails - dynamic cookie domains using Rack

Question

I am new to Rails and Rack, but this guy had a seemingly simple record of using Rack to implement middleware for a dynamic domain session . The code looks pretty good, and I implemented it here on my local machine, but I still can’t go beyond the top level domains in one login.

Here's the code for the intermediate code:

class SetCookieDomain
  def initialize(app, default_domain)
    @app = app
    @default_domain = default_domain
  end

  def call(env)
    host = env["HTTP_HOST"].split(':').first
    env["rack.session.options"][:domain] = custom_domain?(host) ? ".#{host}" : "#{@default_domain}"
    @app.call(env)
  end

  def custom_domain?(host)
    domain = @default_domain.sub(/^\./, '')
    host !~ Regexp.new("#{domain}$", Regexp::IGNORECASE)
  end
end

And then in environment.db:

config.load_paths += %W(#{RAILS_ROOT}/app/middlewares)

Finally, in the production.db (and development.db) file:

config.middleware.use "SetCookieDomain", ".example.org"

Any help is greatly appreciated.

EDIT: I am running Rails 2.3.3 and Rack 1.0
