CSRF token authencity for sub controller

Question

I am getting CSRF warning (resetting my session) in my rails apps whenever I post to my api_controller.rb.

My app is run on iframe in phonegap for windows phone 8 and in my application_controller, I have a p3p header to solve just this problem. But it doesn't seem to work in this case. Its like the p3p is not there...? Has anyone encountered this?

class ApplicationController < ActionController::Base

protect_from_forgery
before_filter :header_fix

protected
  def header_fix
    headers['P3P'] = 'CP="ALL DSP COR CURa ADMa DEVa OUR IND COM NAV"'
  end
end




class Api::ApiController < ApplicationController
before_filter :login_required

skip_before_filter :detect_device
skip_before_filter :detect_browser
skip_before_filter :record_log

skip_before_filter :assign_packages
skip_before_filter :assign_daily_bonus

end

yes the users is login, rails console shows the user id for all events prior to posting — , Apr 05 '13 at 05:25
does it work, when you access the contents of the iframe directly (without the iframe with a browser)? — scones, Apr 05 '13 at 05:30

This gem works for Ruby on Rails (https://github.com/grosser/ie_iframe_cookies). Solves the problem.

Even though my p3p header is valid and my user can login, I am not sure why IE10 does this.
