Hi all, I’m trying to replicate functionality from a previous load balancer in HAProxy, and the final sticking point seems to be the unique ID header. I found the unique-id-header and unique-id-format commands, which are great, but what I want to do is only add a unique-id-header if there is not already one present. If there is one present, I do not want to add another one (which is what seems to be happening by default).
I’ve tried adding a conditional: acl unique_id_missing hdr_cnt(X-Unique-ID) eq 0 unique-id-format %{+X}o\ %ci-%cp-%rt-%pid-%Ts%fp unique-id-header X-Unique-ID if unique_id_missing But that does not seem to be working. Should it? If not, is there another way to go about this? Thanks!
