Best Method to Capture Abandoned Shopping Cart

[Guest]

Hello there,

What is the best method to capture an abandoned shopping cart in .Net 2.0?
I'm using a SQL Session state so Session_End won't work. I thought about
storing the shopping cart in the database and query that periodically, but
i'm afraid of the additional traffic between the web and database servers.
What do you suggest?

Thanks,
David Lozzi
