P3P compliant, still can't read/write cookies from IFRAME as 3rd party document

I have two sites, both with valid P3P policies that passed the W3C P3P
validator, including the P3P compliant HTTP headers test.

On one of the sites, Site A, I have a web page that loads a document from
Site B in an IFRAME. In this context the web page on Site A is the
"originating" document and the web page on Site B is a 3rd-party document
(since it's from a different domain). I thought that having a valid P3P
policy would make IE6 in the default Medim setting, allow cookies from my
IFRAME document from Site B, but apparently it still does not. I am getting
the dreaded "red-eye" and the document from Site B can't read/write cookies
while in the IFRAME.

Is this correct, that you can't read/write cookies from an IFRAME as a 3rd
party document, even if you have a valid P3P policy that indicates no PII
(Personally Identifiable Information) is collected? Or can I fix this
somehow?

Thanks.

Hi Robert,

IFrames, cross-domain cookies, PPI, Medim settings....
What has this to do with PHP?

PHP has nothing to do with cookie-domainsecurity, it is a browserthing.

You might get luckier on another (IE?) NG.

Good luck!
