Netscape works the same way but has less pitfalls. In Netscape you have two
options: just "On" and "Off". In IE, it is more configurable, but at the
same far more obscure what is going on with cookies, thanks to all these
different "Security Zones" under the Tools -> Options -> Security panel. By
default, it selects the medium level for the Internet Zone, which means,
volatile cookies are accepted, and persistent cookies are prompted for.
After having seen the warning 3 times I guess most people click on "disable
this warning" and all persisitent cookies are silently ignored forever.
