Yes, exactly, the web framework can be thought of as a proxy, it is
connecting to the DB using credentials provided by the user.
Which, I will take pains to point out, is far far superior to having it
connect as a super-user and then trusting that the code is bug-free.
Ouch, I don't even want to think about that one.
But anyway, once we arrive at this point you arrive at the standard
questions surrounding session security and the possible use of
certificates. The system is now as secure as your user's password
habits and your server's general security.
