How can I get Javascript to read CGI-generated cookies

michellem has asked for the wisdom of the Perl Monks concerning the following question:

I've been using the standard method for setting cookies using perl/cgi:

$logincookie = $co->cookie
        (
          -name=>'ST',
          -value=>'test',
          -expires=>'+30d'
          -path=>'/',
          -domain=>'www.strategictechnology.net',
          -secure=>0
          );
    print $co->header(-cookie=>$logincookie);

And I'm trying to read the cookie using javascript (via document.cookie), but although it is clear that the cookie is set (looking at the magic cookie file), a javascript function can't read it (document.cookie is empty). What am I doing wrong?
