问题
For the last few weeks I'm trying to locate a problem with session cookie saving in IE. Our application is running inside an iFrame, so the cookies are considered 3rd party.
I'm aware of the P3P header required by IE 6 and 7, but for some reason I still see many IE6/7 users which never save cookies. I'm also unable to reproduce it on our own machines.
I tried the following P3P header: CP=\"IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT\"
Does anyone knows the exact requirements of IE6/7 for saving 3rd party cookies? I couldn't find it anywhere.
Note: I know that this topic has been disscussed many times, and I've read almost any thread on the subject.
Thanks, Shlomi Fruchter
