Be sure to unbuffer STDOUT with 

$|++;

at the start of your script.

    When STDOUT is redirected to the browswer with CGI is it still buffered? I rarely see CGI scripts starting like that, which is why I ask.

      Consider this code: 

      #!/usr/bin/perl -w

$|++;

use CGI;

$q = new CGI;

print $q->header(), $q->start_html(), "before wait<br /><br/>";

sleep 5;

print "after wait\n\n\n", $q->end_html;

      As shown, my browser (Mozilla 1.4) renders "before wait", then several seconds later, "after wait" appears.

      If I comment out the $|++; then all of it shows up in the browser at the same time.
