Depends on what he means by "site". If you have your own domain, then
I'm pretty sure it is specific to your domain.
If you are on a subdomain or, worse, just a subdirectory of a domain,
the other directories on that domain can access the same session data.
Anyway, this is how I understand it. I guess that this might noe
accurate, but think about how wide open all these PHP scripts would be
running on colocated servers if it weren't domain specific.
If you use cookies to store the session ID, that abides by the rules of
cookie access which are domain specific (obviously).
