I have no idea what you did to configure it this way. I wouldn't even know how to do that if you asked me to. As far as PHP is concerned it has no idea which processes are handling which script files at any one point. So whether you request a.php and b.php at the same time or a.php twice at the same time, it makes absolutely no difference to PHP. If you are really seeing this, then the limitation is in your browser or somewhere else. Try making a.php output stuff so it becomes easier to see. As in for($i=0;$i<20;$i++) { echo $i; flush(); sleep(1); } You should see the counter start counting as soon as you hit the page. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
