__autoload not work in cgi?

Hello, I have installed lighttp with php support. It looks like, that function __autoload doesnt work in cgi mode (in the manual I only see, that it should not work in cli mode). I have this code fragment: function __autoload($class) { if(File_Exists(PATH_EXTRAS_CLASSES.$class.".php")) { require_once(PATH_EXTRAS_CLASSES.$class.".php"); } } $CNeplatici = New CNeplatici(); And I get message: 2013-03-27 15:21:14: (mod_fastcgi.c.2676) FastCGI-stderr: PHP Fatal error: Class 'CNeplatici' not found in /usr/local/www/data/sys/web/templates_p/neplatici.php on line 12 (this code is working on other project, but on apache). And if I switch to: require_once(PATH_EXTRAS_CLASSES."CNeplatici.php"); $CNeplatici = New CNeplatici(); It works. I have this lighttp configuration: fastcgi.server = ( ".php" => ( "php-local" => ( "socket" => "/tmp/php-fastcgi-1.socket", "bin-path" => "/usr/local/bin/php-cgi", "max-procs" => 1, "broken-scriptfilename" => "enable", ) ), ) This is cgi configuration not cli isnt it? I thing that autoload should work. Thank you Radek
