I've set a cookie with domain of .example.com. It is available for every first-level subdomain on my site, as it should be.

It is not, however, available on nth level subdomains, i.e. sub.subdomain.example.com doesn't see the cross-subdomain cookie while subdomain.example.com does. Is there any fix for this?
