It would be really helpful if somebody would post somewhere a comprehensive discussion of the session-related issues pertaining to IE. When I google these issues, I get more than 32K hits, so the problem is not rare. I've read some of the posts and tried the suggestions therein, but none of them have helped me a bit, possibly because they are just random guesses.

I don't want debugging help. I'd settle for any professional serious description of what is going on and how I can work around it. I can't imagine that nobody has ever run into these problems before. I'd settle for a semi-professional (but serious) opinion.

In case this isn't clear, my problem is that under IE (and only IE), the PHPSESSID cookie is being quietly rejected. For security reasons, I don't want to pass the session id as part of the URL. Would it help (or be harmless) if I were to explicitly save the PHPSESSID under IE? IE seems to have no problem accepting regular cookies from with my code. Is it time zone related, as some have suggested? Is it because I'm executing files in a subfolder under the main site? I just want to know what's going on, so I can change my setup appropriately.
