Sessions not propagated through different hosts - *Urgent!*

Hi, I posted a message here yesterday, regarding a problem with a site we are developing. I will briefly describe the problem again: We are using two different (physical) computers, each with its own apache web server (and consequently each with its own php module). One of them is SSL secured and the other is not. All the php files that need to be secured (like client registration, contracts, personal information, etc) are on the secured server; all the "normal" files (index.php, product catalogs, etc) that need not to be secured are on the normal server. When someone arrives at the site, index.php (that is on the non secured server) is parsed and a session is created. After a user logs himself in, he/she can access the secured files (i.e. can access he/she's personal information, can buy images, etc). So, when a user (after logging in) clicks the first file that is on the secured server, the login form reapears like the user never got to loggin in the first place. So we have a session that's created when a user arrives at the site and one other when he accesses the secured files. We tried to make both servers' session_save_path to /tmp of the non-secured server but this did not work! Thus the problem is not derived from having two different session_save_path (what about session.cookie_domain - what is it for?). It seems that this happens because we are using two physical different locations for the files, i.e. two different hosts. Wasn't this not supposed to happen?, I mean weren't the files on the secured server supposed to continue the session already created by the "normal" files? Please, this is a very urgent problem we need to solve! Any help, ideas or any contribution is much appreciated (thanks Chris Broussard and Jon Parise for yesterday's tips, but we haven't solved the problem yet!)! If any PHP language developers are reading this we would be very thankfull for your attention!
