Subject:	Shopping cart session handling

I am writing a shopping cart.  I wanted some input on session handling
for a shopping cart that is secure.  

At this time I am not programming for credit card processing.  I am
going to forward onto PayPal for payment initially.  But I want to do a
good job with security.
