IE not accepting 3rd party cookies P3P policy setting

Question

I have a site hosted in http://www.domain1.com

This domain loads a script located in http://www.domain2.com/script.js This sript is loaded with the normal HTML <script> tag method. This script is setting and reading cookies.

The problem is when I view domain1 with IE, the cookies for domain2 are not set. This does not happen in other browsers (FF, chrome, safari).

I tried to fix the issue setting special P3P headers returned by the script.js without luck. What I don't understand is, where the P3P policy has to be set, in domain1 or domain2?

I don't want to set a policy, I just want my cookies to work. Which is the easier approach without touching domain1?

Answer 1

you should set in domain2 ,without touching domain1

for domain2 ,domain1 is a third-party context.

p3p is used to process this,and it's related to user's client setting.
