Hey, funny, I was just going to post something about how cookies function. (a
question that is)
Anyway, I'm wondering:
1) anyone know an easy-to-understand tutorial for learning how to use cookies in
your code?
2) Anyone know f it is possible to use cookies in JSP (rather than a servlet)
Thanks much,
Daniel
