After all, it may still produce output, which the client is supposed to receive.

An alternative approach which was possible in the past was to use http://php.net/register-shutdown-function to handle the request 'cleanup' (which is what I assume you are trying to do) - but since PHP 4.1 this stuff is no longer possible because now this can also send output to the client. Assuming you have a newer PHP... which is highly likely... you could try this instead: <?php ob_end_clean(); header("Connection: close"); ignore_user_abort(); // optional ob_start(); echo ('Text the user will see'); $size = ob_get_length(); header("Content-Length: $size"); ob_end_flush(); // Strange behaviour, will not work flush(); // Unless both are called ! // Do processing here sleep(30); echo('Text user will never see'); ?> ( Shamelessly copied from http://php.net/connection-handling ) The idea is to buffer all the response in memory, then measure the buffer size of the response, then tell that to the server/client, and also let the connection to not support keep-alive. Then throw everything to the client. Since the response is of a given size, and the server/client has got all of it, it has nothing to do further with the server, so it has no reason not to close the socket. HTH, -- Shimi
