ugly hack to set subdomain cookies in Rails 1.2 apps

subdomain_session.rb

module SubdomainSessions
  def self.included(base)
    base.class_eval do
      alias_method_chain :session_options_with_string_keys, :subdomain_sessions
    end
  end

  def session_options_with_string_keys_with_subdomain_sessions
    @session_options[:session_domain] = "." + host;
    @session_options_with_string_keys ||= ActionController::CgiRequest::DEFAULT_SESSION_OPTIONS.merge(@session_options).stringify_keys
  end

end

ActionController::CgiRequest.send(:include, SubdomainSessions)
