Good point - we could always just use the highest prefered address for ftp
and apply the 'round robbin' system just to http.

I think in this case though a better way to do it would be to perhaps get
squid to set an internal counter for each outbound DIRECT request, when it
does greater than (for example) 1000 connections it re-examines the file


to retreive the list tcp_outgoing_address bindings.

This seems a bit ugly and is only one way that you could implement the
'load balancing' that was the subject of the original question.
