Second approach would be to store all the session information (the
products, user info etc) in a database table, and, once the user
gets back from the payment, pickup from there, and restore it's
previous information. But that might mean that the reservation on
products that have taken place (and are deducted from the available
products) will wait forever because the user is not returning.
So a thread would have to run all the time and remove all the
reservations that have not paid in let's say ten minutes.
If you want to run a separate thread to do this type of clean up, I
suggest using Quartz (http://www.opensymphony.com/quartz/) for doing
this. I use it to automate Order Importing and other reoccurring data
integration functions between my WO app and other systems. Quartz has
all the logic in it already for how to schedule, what to do if a job
is interrupted or fails, etc. All you really have to do is write the
business logic for what to do when the scheduler triggers a given job.
I have created a separate WO Application that does this function. It
uses my foundation framework and the Quartz library and has all the
schedule definitions. The actual business logic for the integration is
in the foundation framework so it is easy to manually call the
functions from within my main app if needed, but the automated
scheduling and calling is handled by this Scheduled Tasks application.
Since I'm running it as a separate app, I have to be more careful
about the app and database getting out of sync, but those are pretty
straight-forward issues, common to most any app.
This solution works extremely well for me.
