Squid as http-accelerator - logging Referer as part of access.log?

I'm using Squid to accelerate Zope, and I must say it's working wonderfully
(10 times as fast as Zope!).

Only downside is that I can't get the referer out of the access logfile in
httpd mode, which is useful info for web server analysis (e.g. what search
terms brought your site up.) Any way to get Squid to log this info the way
Apache or Zope do?
