transparant session propagation and headers

hi all, If a client doen't accept cookies and transparant session propagation is enabled, links are changed to include the SID. But this is not the case while redirecting clients. This results in session loss unless you manually add the session id to the redirect url. Not really transparant... I was wondering if this is correct behavior or a bug in php. currently this happens for sure with os x server & php 4.3.2 - 4.3.9, but i have seen it before... bas
