Well,
Since the entire site (my own) is based on sessions, i guess customers checking out must have accepted cookies.
So i guess the session will stay alive.
It's quite important because when the customer returns, he/she should be able to download whatever he/she selected to begin with, which on the site is identified by session_id();
On the site, i create directories named after the session_id(), so the customer should get into that specific dir.
