Is it possible to detect whether cookies are enabled in Internet Explorer through the IWebBrowser2 Interface or through some other WebBrowser Control C/C++ interface? I can't see any obvious way to do it, but was wondering whether there is a subtle way.
You can pass the URL to InternetGetPerSiteCookieDecision() and it should tell you what the policy is for that site.
It is a pretty terribly named API. :-/
