What is a good way to track the shopping cart for an unregistered user? For a user session it is easy, but what if the user logs in, adds a few items in the cart, and decides to terminate the session and then returns later?
What are some of the design trade-offs? Bharat
I would probably make that kind of session expire quickly and add a method to remove that from the db after a certain time period. I have a prod app that I am working on fora company that keeps the sessions in the db and we wrote a task that deletes all session older than like 90 days I think or something like that.
Hello Chris, Thanks for the response. Yes it is a good idea to expire this kind of session data. My question was more about how to track an anonymous user across sessions reliably. The only thing that I can think of is doing this based on the IP address which can be unreliable? What if there are a number of users coming via the same gateway working in the same office? Appreciate your thoughts on this. Bharat
You could assign each session a random number for each one.
Semi-reliably: set a persistent cookie with the session/cart id.
