Then you have configured your server to always turn on output buffering or your test script is bad.

I don't think it's either, but I'll let you decide. I tried a new test with your code and some slight modifications: <?php header('Location: http://www.php.net/'); $fp = fopen('/tmp/log.txt', 'w'); for ($i = 0; $i < 30; $i++) {

    $str = "Count $i\n";
    echo $str;
    fputs($fp, $str);
    sleep(1);
    flush();

} ?> Basically, I'm only looping 30 times, but I'm sleeping for a second and flushing the buffer each time. The result is a response that looks something like this: HTTP/1.1 302 Found Date: Fri, 02 Sep 2005 18:12:02 GMT Server: Apache/1.3.33 (Debian GNU/Linux) Location: http://www.php.net/ Transfer-Encoding: chunked Content-Type: text/html; charset=iso-8859-1 8 Count 0 8 Count 1 8 Count 2 ... 9 Count 27 9 Count 28 9 Count 29 0 This result is not buffered on the server by PHP or Apache - each of these chunks are received about one second apart, and the headers are received barely more than one second after the request is sent (only because I didn't flush before the first sleep): [2005-09-02 14:12:07] [+0.004467 seconds] HTTP Server: socket_read() ...

This happens a little more than 30 seconds after the request is sent and a little more than 29 seconds after the HTTP response line and headers (including Location) are received.
