Win2K and trans_sid

I am running Apache 2.0.47 with PHP 4.3.3 on a Windows 2000 server, and I am having some trouble getting cookie-less sessions to work. I've search around trying to figure out how to get this to work, but most of what i have found is people going to other way. To be clear, I am trying to use PHP sessions *without* cookies (none at all). To do this I have set use_cookies to 0 and use_trans_sid to 1, but all that does is break sessions altogether. Is there a way to get this to work? What am I doing wrong? Is what I am trying to do even possible with the PHP session handler? Any help or pointers would be greatly appreciated. ahp
