HTTP_Session - session replication

Hi, Firstly, thanks to the authors of HTTP_Session. My testing with it has been flawless. I have been using the MDB2 container and I can watch my session data being created and destroyed in the sessiondata table. Before session data is destroyed, I would like to replicate it in another table so that it can be recovered at a later time for some post-processing. Is there a preferred way to do this? Maybe I need to extend HTTP_Session with a custom procedure? I would really appreciate hearing how others have approached this, assuming I'm not the only one with this need. In case some additional context helps... I have a session that contains customer order data. I am connecting to PayPal to process the payment and it later notifies me via its Instant Payment Notification (IPN). This is asynchronous. When I get notified, I would like to restore the session data to perform post-processing. However, I can't rely on the session record that has already been saved, since a user may prefer to continue shopping, in which case the previous session must be destroyed. Hence, I need to replicate it before destroying the session. Thoughts? LFaR.
