Class P3PUtil

P3P is (was) a standard for describing policies for websites http://www.w3.org/P3P/details.html IE 6-8? uses those headers for determining if cookies should be accepted when a page is loaded inside an iframe (depending on security level) This class tries to address this problem by inserting an acceptable header that allows ie to accept headers.
