Session variable is lost on RedirectToAction in IE

I’m using MVC3 and the application is called from an external PHP website (form – post).
I’ve got this:

Internet Explorer 9 (9.0.8112.16421 update 9.0.3)

Home controller – method Index(string A, string B, string C) is called.
Values are fine and are stored on the session (Session[“A”], …).
Redirect to Login controller.

Login Controller – method Index() is called.
Session values are just lost (null)

Internet Explorer 8, Chrome & more

Home controller – method Index(string A, string B, string C) is called.
Values are fine and are stored on the session (Session[“A”], …). Redirect to Login controller.

Login Controller – method Index() is called.
Everything works fine (values are stored on the session)

Notes

This ONLY happens when the form is inside a PHP page on another host (maybe another OS but can’t say for sure) with IE 9 but while inside our intranet host (IIS) or a cloud host (also IIS) there is no problem at all (even with IE9).

I’ve created a sample code on the view as bellow:

@{
   if (Session != null)
   {
       foreach (var item in Session.Keys)
       {
           ViewContext.Writer.Write(String.Format("{0}<br />", item));
       }
   }
   else
   {
       ViewContext.Writer.Write("Session = null");
   }
}

Using IE8, Chrome and others, all keys are there.
But using IE9 there is nothing at all, but the session is not null too. It’s just empty.

Any help?

After a deep search into google I’ve found:

Session variable is lost on RedirectToAction in IE

Cookie blocked/not saved in IFRAME in Internet Explorer

Both get into the same core problem. Frames.
After removing the frames from the page variables worked just fine.
