Hi Marc,
Following on from our discussion about the p3p policy on ads.hub.org, it
looks like one reason they might not be working is that the server is
not outputing a p3p line in the http headers- see
http://validator.w3.org/p3p/20020128/p3p.pl?uri=http%3A%2F%2Fads.hub.org
on the other hand, doubleclick.net output:
P3P:CP="CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV
OTC NOI DSP COR"
Of course, this would have to be altered for ads.hub.org as per
http://www.hub.org/hubpolicy.php
according to the validator there is also a policyref="URI" directive
(that doubleclick are not outputting).
Regards, Dave.
