I would just add a link like this to your dynamiic page:

<a href="/cgi-bin/myscript.pl/logfile.txt?request=download">
Click here to download</a>
[download]

This link will call your script and pass it the name value pair request=download. If you then have the script print out the file as shown in the links you are done. The extra path info after myscript.pl gives the download file its name.

# add this to the script

if ($q->('request') eq 'download') {
    &DownloadFile( $filepath, $filename );
  exit;
}

sub DownloadFile {

    my ($filepath,$filename) = @_;
    my $filesize = -s "$filepath/$filename";

    print "Content-disposition: attachment; filename=$filename\n";
    print "Content-Length: $filesize\n";
    print "Content-Type: application/octet-stream\n\n";
    my $buffer;
    open FILE, "$filepath/$filename" or die "Oops $!";
    binmode FILE;
    binmode STDOUT;
    print $buffer while (read(FILE, $buffer, 4096));
    close FILE;
}
[download]
