$r->rflush() works fine for me.

This works for me, showing the results as they come, under Apache::Registry.

my $r = shift;
$r->content_type('text/html');
$r->send_http_header;
...
$|=1;
if (open (FILE, "/usr/sbin/traceroute $host 2>&1 |")) {
print while ;
close FILE;
}

I think there's a Net::Traceroute on CPAN, might want to check that out to
avoid the fork.

One of the reasons that I always like the nph- construction is that is
showed the traceroute 'live' like it would from a console.  Last I checked
perl doesn't show the traceroute result until the sessions complete which
could be a long time if there is trouble in the trace.  Did you find a way
to get past that?

That would be great!  Any idea when it will be ready?

I'm getting ready to port an old and somewhat clunky traceroute CGI script
to mod_perl, mostly to avoid the horrid 'nph-' construction. If you'd like
I can make the source available.
