First, the default session handler stores data on disk, not in memory.
Not sure if restarting the webserver trashes them or not.
Cookies would not suffice for this much data. The size of each cookie and
the number of cookies allowed per site is limited. Not sure on the actual
limitations in modern browsers, but you probably shouldn't store more than
20 cookies, and they probably should not exceed 1024 bytes per cookie.
Furthermore, all the cookie data is transmitted from the client on each
hit, so there are practical limitations with bandwidth as well.
