I am certain I'm missing something important about the <If> directive and the -ipmatch operator when used in conjunction with %{HTTP:X-Forwarded-For}. Please permit me to illustrate the problem by way of example: <If "%{HTTP:X-Forwarded-For} -ipmatch '10.0.0.0/8'"> LogMessage "Got IP match [%{HTTP:X-Forwarded-For}]" </If> <Else> LogMessage "No IP match [%{HTTP:X-Forwarded-For}]" </Else> produces the following log output: [Wed Sep 04 17:57:03.611095 2019] [log_debug:info] [pid 11134] [client 10.128.10.9:53515] No IP match [10.128.10.9] Clearly X-Forwarded-For has the value '10.128.10.9', which is certainly within the 10.0.0.0/8 CIDR. So I say to myself "Well, maybe -ipmatch doesn't really like a CIDR, despite what the documentation appears to say". <If "%{HTTP:X-Forwarded-For} -ipmatch '10.128.10.9'"> LogMessage "Got explicit IP match [%{HTTP:X-Forwarded-For}]" </If> <Else> LogMessage "No explicit IP match [%{HTTP:X-Forwarded-For}]" </Else> This produces the log message: [Wed Sep 04 17:57:03.611108 2019] [log_debug:info] [pid 11134] [client 10.128.10.9:53515] No explicit IP match [10.128.10.9] So with X-Forwarded-For clearly containing the value 10.128.10.9, I cannot match 10.0.0.0/8 or 10.128.10.9 with -ipmatch. Maybe -ipmatch doesn't work? <If "'10.128.10.9' -ipmatch '10.0.0.0/8'"> LogMessage "Got dummy IP match" </If> <Else> LogMessage "Failed dummy IP match" </Else> produces the following log message: [Wed Sep 04 17:57:03.611112 2019] [log_debug:info] [pid 11134] [client 10.128.10.9:53515] Got dummy IP match So it appears there's something pathological about %{HTTP:X-Forwarded-For}, but I can't help but observe that it prints as I expect it to in the LogMessage output. Here's another example: <If "%{HTTP:X-Forwarded-For} == '10.128.10.9' "> LogMessage "Got string IP match [%{HTTP:X-Forwarded-For}]" </If> <Else> LogMessage "Got no string IP match %{HTTP:X-Forwarded-For}" </Else> yields [Wed Sep 04 17:57:03.611117 2019] [log_debug:info] [pid 11134] [client 10.128.10.9:53515] Got no string IP match 10.128.10.9 I'm convinced there's something subtle I'm overlooking, and would be very grateful for any suggestions. Would some kind soul come to my rescue?
