Alfred, not at all. It is easy to set up things up so AOLserver logs
the OpenACS user_id to the access log for every single hit. I've done
it on sites I've run.
As far as I know, Vadim Nasardinov first came up with the
method,
back when we worked together at aD. :) It's since been
discussed
several
more
times.
Hm, maybe I should add this to the toolkit, with a simple config
switch to turn it on/off...
