Cookie issue with two website from different domain, one called in another

[gagandeepgupta16]

Hi
I have one website -A in which there is an Iframe.
1. If i call another website -B inside the iframe in A then cookie is not getting created.

2. If the same website B is directly opened on browser the cookie is created.

3. If i go for 1. scenario and reduce the privacy setting of the browser (IE 7) by selecting "Allow session cookie..." then also cookie is created.

The issue is i can ask the end users to reduce their browser's security or Privacy settings.

Is there any possible solution like one i got by adding P3P using <cfheaders...
but somehow its not working.

Any help would be appriciated.

Thanks in advance

So finally i got the solution,
After a long google search i found this site which gave me the best solution :

http://viralpatel.net/blogs/2008/12/how-to-set-third-party-cookies-with-iframe.html

and then i went to

http://www.webentrust.com/p3ptools/compact/builder.html

to generate my own set for the <cfheader....

Let me know if anyone of you ever have similar sort of issue....I'll be glad to hellp...
Happy Coding... :-)
