Ah, most excellent, thanks!  Callback support is not quite there in
Mac::Glue, but we can do it just about as easily without it:

#!perl -w
use File::Spec::Functions;
use Mac::Glue ':all';
use Mac::Events;
use strict;
my($url, $file, $text, $n, $done);

$url = 'https://pause.kbx.de/';
$file = catfile($ENV{TMPDIR}, "pause.html");

$AppleEvent{'WWW?', 'URLE'} = sub {
    my $dobj = AEGetKeyDesc($_[0], keyDirectObject);
    my $got  = $dobj->get;
    AEDisposeDesc $dobj;
    $done++ if $got eq $url;
    0;
};

$n = new Mac::Glue 'Netscape Communicator';
$n->register_url_echo('McPL');
$n->geturl($url, to => $file);

while (1) {
    last if $done >= 2;
    WaitNextEvent;
}

$n->unregister_url_echo('McPL');

{ local($/, *F);
    open F, "< $file" or die "Can't open $file: $!";
    ($text = <F>) =~ s/\015?\012/\n/g;
}

print $text;

__END__
