I'm using the %rt field in the "unique-id-format" config parameter (the full value is "%{+X}o%pid-%rt"), and am getting lots of duplicates. In one specific case, haproxy added the same http_request_counter value to 70 different http requests within a span of 61 seconds (from various client hosts too). Does the http_request_counter only increment under certain conditions, or is this a bug?
This is with haproxy 1.5-dev19 -Patrick
