Sadly, no browser follows this logic, and domain=example.com (http://example.com) is exactly equivalent to domain=.example.com (http://example.com). There is no way to limit cookies to a single DNS name only, other than by not specifying domain= value at all - and even this does not work in Microsoft Internet Explorer; likewise, there is no way to limit them to a specific port.

packages.python.org can set a .python.org cookie which www.python.org will read.
