What Ben Wright proposes is a clear violation of the P3P
specification and many have suggested that this so-called
solution would likely be viewed by the FTC as a deceptive
practice. This is because his solution involves creating
a P3P "compact policy" that will get through IE6's
cookie blocking filters, but includes an extra token
(ignored by IE6) that basically means "just kidding."
The P3P spec is clear that unknown tokens do not change
the meaning of the P3P compact policy. Therefore,
a web site is still making a statement about its privacy
practices if it issues a P3P compact policy, even if
it includes Ben's extra token or crosses its fingers
behind its back. Members of the P3P working group have
discussed this with Ben, and he obviously disagrees with us
as he is continuing to advertise his solution and his web site
where you can buy his 30 page monograph for $49.95.
