On both IE and Chrome, if I allow 3rd party cookies from the browser's settings I can login.
However, this isn't a practical solution.
Regarding IE: Do I need to create a P3P policy and reference it in my iframe website?
Regarding Chrome: Chrome has always worked fine. Did they change their cookie policy recently?
I have always been able to login to my iframed website. Did anyone else experienced this behaviour?
Any help appreciated, cheers.
