It is actually Internet Explorer that needs to receive 256 bytes before
displaying anything. If you test your page with a different browser (like
Mozilla), you'll see that the Flush() works with less data too.
How did you know that? Are quirks of IE and other Microsoft products
documented anywhere? I wouldn't know where to start in the MSDN.
It is not documented as far as I know.
I know this because I rewrote the ActiveState Visual Package Manager from
scratch (For Komodo 2.0 Professional and PDK 5.0). It uses HTTP::Daemon
to act as a mini webserver. When you install/upgrade/remove packages, I
wanted to see some kind of progress report in the browser window. I could
see this immediately on Mozilla, but on IE only after a couple of packages
had been processed.
After changing the code to something like this, everything works on IE,
Mozilla (and Opera, if we ignore keyboard events):
my $res = HTTP::Response-new($RC_OK, $MSG_OK, $headers, undef);
$conn-send_response($res);
print $conn HTML;
