Cookies in Iframe page loaded with Curl

Cookies in Iframe page loaded with Curl

On http://aegon.nl you'll get an opt-in which only displays when you
haven't got the right cookie set for the website.
Now I'm trying to load the website in an Iframe with an injected file (to
do some fancy stuff with javaScript). To be able to do that, I need to
CURL the sourcecode and change the base href to "aegon.nl" in order to
show the same layout (for the url's to the stylesheets and such).
Now, been there and done that. But now I've got a problem with the
cookies. I can click the button in the opt-in as many times as I want, but
It keeps coming back. Ofcourse I only have this problem when I load the
page in the Iframe. After searching the sourcecode I think I found the
problem:
var
dom=(window.location.hostname.indexOf(".")>0)?'aegon.nl':window.location.hostname;
var AEGONCookieSettings = new AEGON.CookieOptIn(dom)
Probably the problem is solved by changing this part of sourcecode.... But
that doesn't solve the problem for the other websites which are using the
same kind of opt-in.
Does anyone have a solution for this?
