I am in the process of changing my cookies (stored on my users’
browsers) so they can be shared across multiple servers under my
domain. So, instead of writing cookies with domain
‘www.mydomain.com’, I am writing them to ‘.mydomain.com’ so they can
be read by www.mydomain.com, www2.mydomain.com etc. During the
transition, I need to be able to retrieve cookie values stored for
the main domain and the subdomain.
Browsers will store cookies from ‘www.mydomain.com’ and
‘.mydomain.com’ separately, and return multiple values if the target
servername matches the hierarchy. However, I cannot find a way under
CGI.pm or CGI::Cookie to retrieve these multiple values – only one
value is ever returned.

Is there a method to get CGI.pm to fetch all the values in the
request, or am I forced to use the environment variable?
I would guess that the problem is that they share the same name. I don't
know if you can have CGI.pm help you, but OTOH it's not that difficult
to grab the values:
my @cookie_values;
for my $pair ( split /;\s*/, $ENV{HTTP_COOKIE} ) {
my ($name, $value) = split /=/, $pair;
s/%(..)/chr(hex $1)/eg for $name, $value;
push @cookie_values, $value if $name eq 'var';
}
