Yeah the session files are cleaned up automatically but your application
doesn't know that. You'd have to specifically tell your application (via
a cron job??) when the session get cleaned up and that it (the
application) should remove all the old carts.
Is there something I don't know about (very possible!)? I mean, even if the users session file is deleted, how do you tell the app. to follow suit and delete it's ASIDE from setting a cron job?
Rather than storing the shopping cart in a DB, store the cart in the session. When the session dies, so does the cart.
When/if they choose to save it, it THEN gets ported into a database.
