help please - strange session behaviour on IIS with php4.1.2

i've written a simple script, which tests the session behaviour on the IIS, since it didnt seem to work the following script should increase the session-var $testVar and display it but it always stays at the same value can someone explain that? is that a bug? also if i would increase $_SESSION['testVar'] it doesnt work. i have been looking at the server and the session-file is also updated, but not with the new values, only the timestamp is updated, it seems session_start(); // make the session variable globally available // we have register_globals = Off $testVar = &$_SESSION['testVar']; // init testVar to 1 or increase it if( !isset($testVar) ) { print 'set testVar to 1<br>'; $testVar = 1; } else { print 'increase<br>'; $testVar++; } // i can put session_register before // or after the 'if' it always happens the same session_register('testVar'); print $testVar; the environment: - IIS-Server5.0, WIN2k - PHP4.1.2 - session.auto_start = 0 - register_globals = Off i am using the recommended-php.ini, that's why register_globals is off thanks for help -- Wolfram ... translating template engine .... http://sf.net/projects/simpletpl ... authentication system .... http://sf.net/projects/auth
