It works now, thanks Diez. I need to speed up on my python skills I feel dumb now.
On the other hand, I don't feel right to store the whole cart in the session, I have it in a table, I don't know how much memory would I been using if all cart-items where stored in memory. Although I've seen a data directory created at root directory, where I guess, all sessions are stored. Juan Pablo On Oct 10, 3:27 am, "Diez B.
