P3P Cookies

If we use the HTTPOnly flag for XSall perhaps we also have to add P3P headers. Just studying the topic now. Here are some links: P3P, Cookies and IE6.0: A Case Study Don’t get trapped by mixed headers

HTTPOnly ?

The XSall implementation of OpenSignOn is not using the HTTPOnly flag now. I don’t see any XSS problems but perhaps it would not hurt to implement it. An extra wall always helps.
