RE: [squid-users] squid proxy - multiple outgoing IP addresses

One thing I think needs to be made clear balance_on_multiple_ip ONLY makes
squid select different remote serve IPs from the DNS results of looking up
that domain name per-request. It does nothing towards the OS selection of
Squids' outgoing IP.

For example; say example.com has 2 IPs (*.1 and *.2). With that setting
turned on.
 Squid fetch http://example.com/ from *.1.
 A second client request for http://example.com will fetch from *.2
instead.
 A third client request will fetch from *.1, etc etc.

Squids outgoing IP will be the system default for all three+ requests.
