Air + Ipad + RemoteObject problem with session cookies

I am making Air version for IPad of a Flex application.

My flex application needs session from an secured enterprise proxy, without that session none remoteObject requests can pass the proxy and reach blazeDS.

My solution for flex works fine: calling an enterprise  servlet at application´s startup to obtain a cookie session. I use a POST call to the servlet using URLRequest (sending the user and password parameters), the servlet responds with  a message with a session cookie, and from that point, without me having to code anything more, my flex application get that cookie with the session that automatically is loaded in my browser cookie stack, and that transparently is used from all my subsequents remoteObjects calls in the flex application.

In my Adobe Air Ipad version, this just does not work, the session or is not storaged or is not attached with subsequent remoteObjects requests.

- I´m forcing request.manageCookies = true

- I´m working with the IOS simulator (Is there any difference for cookies with a real Ipad device?)

- I´m using Flex 4.6.0, Air 3.5, IOS 6, Ipad 3, BlazeDS 4.0, Java 6 BackEnd.

.. What´s the problem/difference with Air+Ipad from the flex version?
