[Webware-devel] Session expiration handler

[Michael Engelhart]

Hi all -

I'm new to devel but have been using Webware for a month or so.

One thing I missed from our Java brethren was session expiration hooks where when a session is expiring or being invalidated an event was fired to a method that your app could implement. I found the addShutdownHandler() method in Application.py and took that simple mechanism as model to add a addSessionExpirationHandler() method to Session.py. All in all it's almost identical in functionality to the Application.addShutdownHandler() method concept.

I've done some trivial testing and it works very well. I have tested it for closing database connections, ldap connections, etc. I realize that some of these are kind of silly because most of those connections shut themselves down anyway when they are gc'd but that was what I used for testing as I could watch the results. Possible uses would be say someone fills a shopping cart and then fills out their name and address info and click continue to enter their CC information but their browser crashes and they don't feel like typing everything in, this hook could take that Session data and generate an HTML email to send to that user asking if they want to finish the transaction.

Anyway, I'm wondering if I can post the diff from Session.py here or how I could get this added to Webware?

Thanks
Mike
