Third-party cookie, P3P and Internet Explorer 7, a solution.

I nearly got crazy about that sh*t.
The goal was to bring up a tracking pixel to see the movement of single users. For that reason, you’ll need to set a cookie and read it on the page. In my case, the tracking pixel comes from another machine, than the website.
After I generating the p3p file with the ibm p3p generator, I checked and validated that stuff.
Normally that should work right now. It does in Firefox! But it doesn’t in Internet Explorer. After searching around, I found out, that I can also set the P3P stuff via the header, but that’s not all. You’ll have to send it on the site where you set the cookie and even on the page, you receive the cookie.
This is my header:

header ('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"');


Good luck!
