The documentation mentions the 'domain' attribute is available.


Read some general documentation about cookies to work out what it can be set to.

In short, by default you cannot share a cookie between two distinct
hosts, you can however share it across hosts in same parent domain by
setting the 'domain' to the parent domain.
