Re: Usefulness of $r->notes and $r->pnotes (or $c)

We use the notes table to put a reference to the session (and thus the user)
in the access log.

$request->notes->set('session' => $session->{SESSION});

This is in apache2.conf:

  LogFormat "%v:%p %h %l %u %t \"%r\" %>s %b \"%{Referer}i\"
\"%{User-Agent}i\" %{session}n" combined_with_session

This makes it possible to differentiate log entries by user, whether
multiple users have the same ip address or if a user's address changes.
