You can also use threads, like in ztk-BBC-World-News-Rss-TickerTape

You can also use a callback in the LWP's request statement. Just sprinkle "$mw->update" frequently in the callback. This is a clunky solution, because of what may happen if the network connection hangs. 

#!/usr/bin/perl -w
#from lwpcook 
use LWP::UserAgent;
$ua = LWP::UserAgent->new;
$URL = 'http://zentara.net/zentara1.avi';
$filename = substr( $URL, rindex( $URL, "/" ) + 1 );
#print "$filename\n"; 
open( IN, ">$filename" ) or die $!;

my $expected_length;
my $bytes_received = 0;
my $res = $ua->request(HTTP::Request->new(GET => $URL),
    sub {
        my ( $chunk, $res ) = @_;
        $bytes_received += length($chunk);
        unless ( defined $expected_length ) {
            $expected_length = $res->content_length || 0;
        }
        if ($expected_length) {
            printf STDERR "%d%% - ", 100 * $bytes_received / $expected
+_length;
        }
        print STDERR "$bytes_received bytes received\n";

        # XXX Should really do something with the chunk itself 
        print IN $chunk;
    }
);

print $res->status_line, "\n";
close IN;
exit;
