Well, you haven't told us much about your webapp. Are you using
connection pooling? If so, then you'll need to provide the webapp
userid as an additional parameter to your database updates. If you are
not using connection pooling, such that your webapp userids are
connecting as themselves, then the problem becomes much easier; you've
got the correct userid to log by just looking at the connection details.
