Ok, that sort of worked. I have a pair of load balancers sitting in front of my Squid proxy farm. The load balancers insert the X-Forwarded-For header into each HTTP request which allows Squid to log their connections using their real client source IP (extracted from X-Forwarded-For). In reality, the connections to the squid servers are being made directly from the load balancers. When I use log_access to deny logging to the load balancer's IP addresses, -nothing- gets logged to access_log. I am attempting to not log the "health HTTP checks" from 10.26.100.130/10.26.100.131 but still log the other traffic. It doesn't seem that log_access is X-Forwarded-For aware? Any ideas? acl loadbalancers src 10.26.100.130/255.255.255.255 acl loadbalancers src 10.26.100.131/255.255.255.255 log_access deny !loadbalancers Thanks, Josh From: "Baird, Josh" <jbaird@xxxxxxxxxxx> > I am trying to ignore requests from two IP addresses in my access_log. > These two hosts connect every second and do "health checks" of the > proxy service and I would like to eliminate the access_log spam that > theycreate. > Here is what I am trying: acl loadbalancers src > 172.26.100.136/255.255.255.255 acl loadbalancers src > 172.26.100.137/255.255.255.255 access_log /var/log/squid/access.log squid > !loadbalancers This does not seem to have any effect.
