That doesn't seem to quite work. I wrote the follow test: 
#!/usr/bin/perl 
 
$|=1; 
 
print "Content-type: text/html\n\n"; 
 
for (1..20) { 
        print "$_<br>\n"; 
        sleep 2; 
}

[download]
and the browser still waits until all 20 numbers are outputted before returning the page.

This is under IE 5.0, Perl 5.005 and Apache 1.3.19.

Update: If I increase the range to something higher, I find that around 40 or so, it's starts to output. Apache itself must be doing some buffering ...
