Hi Martin,
HAProxy can report an 'id' of a backend and of a server.
You can give a try to this:
http-response set-header X-Backend-Info %[be_id]/%[srv_id] if { src
10.0.0.0/24 }
It should add the following header if the first server of the first
backend was used:
X-Backend-Info: 1/1
IDs can be forced in HAProxy's configuration using the directive 'id'.
You may even be able to convert a backend id to a string using a map:
