Assistance Needed (not sure where to ask)

Hello, We are developing a web server (for the past 5 years off and on), and the latest version supports ISAPI, and now PHP. I have everything working wonderfully - but have a problem, and not sure where/who to ask. When a PHP script does: setcookie($cookiename,$sessid,'',$cookiepath,$cookiedomain,$cookiesecure); or header("location: $ref"); It appears my server code is not implementing something correclty. Would you mind giving me some insight on what exactly I might be missing? We are very interested in promoting PHP with our web server, and have already helped some customers move from IIS & ASP to our webserver w/ PHP. I have developed all of their PHP using session variables. But I have had a couple customers say the above code is not working from well known PHP scripts (like phpBB and NukePHP), so I am sure it is not their issue it has to be mine. Basically in a simple test script, tracing my server code during exection I never see an ISAPI event for those - which leads me to think, I am not interacting with your ISAPI PHP correctly. I have written some test ISAPI's and they are working flawlessly, so I must not be calling your code correctly. Who can help me? As I am extremely excited to announce that our latest version is 100% compliant w/ ISAPI and can host PHP based sites. (I have successfully implemented almost every PHP example using every extension, but these two commands have me baffled on what did I not do correctly). Thanks greatly for your assistance!!
