Thanks for the response. The idea is to make entries in origin's access log easily distinguishable and usefull. The prototype I've is as follows: Anything from my squids to their origin servers should have a "Bill-To" header, something like, ~$ curl -v http://192.168.1.100/index.html -o /dev/null --header "Bill-To:Western" --silent * About to connect() to 192.168.1.100 port 80 (#0) * Trying 192.168.1.100... connected * Connected to 192.168.1.100 (192.168.1.100) port 80 (#0) GET /index.html HTTP/1.1 User-Agent: curl/7.16.4 Host: 192.168.1.100 Accept: */* Accept-Encoding: deflate, gzip Bill-To:Western <---------------------- The origin server would then log it in its access log as: Bill-To:Western host:192.168.1.100 virt:127.0.1.1 <snip> Thx../ 2008/12/17 Amos Jeffries <squid3@xxxxxxxxxxxxx>: >> Greetings, >> >> I've squid running in non-transparent mode.
