SID without cookies - why sometimes automatic?

I'm using PHP4's sessions but am having a problem when cookies are disabled. On my development machine (Win ME, Apache, PHP4.0.6) SID (i.e. PHPSESSID=980324....) is automatically apended to all links on the PHP pages, however on my hostrocket.com web server account (Linux, Apache, running PHP4.0.5 if this has any bearing) it's not. I checked phpinfo() and all session variables are the same on both servers. Do you have any idea why this is happening? I know I can append ". SID ." to each link, but doing so causes SID to appear twice on each link on development machine, and just the once on your web server. Is there perhaps some configuration I can change on the web server? I obviously prefer the way the development machine works because it saves me having to go through every link adding SID, but my main priority is just to get both machines to work the same.
