Hi Casey!

If you use Netscape you have an option to let netscape ask before
accepting a cookie. The content of the cookie is displayed in
the popup window then.

It's not the cake, just a cookie ...
A cookie is a small key=value pair. If its used for session
management a small unique string is generated representing your
session. This session key is used to as a key to get data stored
with session scope on server side.
>what data goes into a cookie and what doesn't?
If you just use sessions its just a unique created string and nothing
from your data.

Depends on the server, I guess normally they will stay in memory,
so keep them small and use these beans as proxies to real data somewhere.

Yes, one instance per application, so in your case: one instance.
