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. -- Kelly Hallman
