Sessions do not work

Hi! I know that this is not the windows mailing list, but because I think my problem has nothing to do with the servers i am using, I am asking for help here too. I want to use sessions, but I have the following problem. I tested my script at home (Win98SE with Apache and PHP4RC2) and everything was alright. When I tried to put that script on the server at work, the server replies with nothing. It executes the script but NOTHING is send back to the client. I couldn't believe it, so I tested it again using telnet (GET /session.php HTTP/1.0), but the same again, the server send back nothing, not even the HTTP/1.0 OK message or something like that. The server ( WinNT5 with IIS5 and PHPRC2 ISAPI Module) has the same php.ini file I am using at home, the path for the session file is also correct and PHP has the right to write there. What could be wrong? This is the simple script I used to test sessions: <script language="PHP"> session_start; session_register("count"); echo $count++; </script> Please help me, this is very important...
