Hello,
yes, H2 behaves very differently; due to protocol differences but also due to other changes. In the beginning H2 was only implemented in the frontend and every transaction was downgraded to HTTP/1.1 internally. This was later changed to an internal generic "HTX" representation that allowed to unify the protocol stack. To return relative URIs form in the logs, I guess you could reconstruct the string manually with pathq (untested): \"%HM%[pathq]%HV\" as opposed to %r pathq is a HTTP sample designed to do exactly this, always returning the URI in a relative format: http://docs.haproxy.org/2.6/configuration.html#7.3.6-pathq Not sure what %HU does, I assume it refers to the url not pathq. I agree that doc updates are needed at least in section "8.2.3. HTTP log format" and "8.2.6. Custom log format". Lukas
