Well, you should be managing all your cookies, so here's the quickest way I can think of:

use CGI;

my $c = CGI->new();
# Make a list of all our cookies;
my @_COOKIES = qw(cookie1 cookie2 cookie3);
my %COOKIES = ();
foreach my $cookie (@_COOKIES) {
   my $value = $c->cookie($cookie);
   $COOKIES{$cookie} = $value if $value;
}

That's a pretty quick, cheap hack but should work..
