Hi Guys,

I am implementing a solution basically for x-domain sign in using iFrames. So its like domain A.com is served into an iFrame in Domain B.com with the aim that a user who is logged in a Domain A.com is also logged into B.com iframe.

At the moment - its working fine in FF and Chrome - but IE is causing me headaches. So I have a P3P policy implemented but whenever this is served up - it still wont login on Domain B.com. Domain B.com gets a fresh session and it's not logged in.

I have set a P3P policy on Domain A.com when the user logins - and I set it using

policyref="/w3c/p3p.xml", CP="ALL DSP COR CURa ADMa DEVa TAIa PSAa PSDa OUR IND UNI COM NAV INT DEM"

I am using

response.Appendheader

Is this correct or ? Should I be using something else ? Really stuck
