What you're seeing is the domain value of the cookie (see CGI::Cookie).

Yes, exactly. And that's what I meant when I said, "Apparently, the cookie sent is dependent on the server requested. It might be better to always send a cookie for the domain instead."

When the cookie's domain attribute is set to the domain name of the server, the cookie is often referred to as a "domain cookie" and when it is set to the hostname, the cookie is sometimes called a "host cookie" or "server cookie".

The word "domain" has dual meaning as one of the cookie attributes and as a DNS term.
