I'm baking a
cookies.txt file for use with some
wget scripts and can't find a lot of detailed information. Currently, I'm trying to determine the difference between "
domain.tld"-style cookies and "
.domain.tld"-style cookies (with and without leading dot).
I've pulled a bunch of cookies from Firefox's database and there doesn't seem to be any consistency, even within the same domain. For example, this very site sets a cookie named "
user" for the domain "superuser.com" and another called "
__qca" for the domain ".superuser.com".
What is the significance of the leading dot? Is it perhaps related to the "can be read by other machines at the same domain" column in
