URL rewriting & logging

[Robert]

Hi,

  I'm trying to use Eagle book-like URL rewriting to track sessions and
I'd like to log session id in the 'user' field (so Analog can do all
kind of usefull stats about sessions). I hoped I could just set 'user'
throught Apache::Connection's user method, but it seems to be read-only.
Is there any simple way to make Apache log some knowN string (say
$ENV{SESSION_id}) to the user field? Or do I have to write complete
LogHandler for it? Thanks for your help.
