1. The problem I’m having:
I am trying to use a variable to build a custom key for a cache plugin - this is not yet merged by @darkweak.
While testing the PR I noticed that my variable is not seen by the plugin, although it is available to be sent as additional custom header.
I also tried to set the variable through vars with the same result.
Am I missing something? Did I misread the caddy order?
2. Error messages and/or full log output:
$ curl -IX GET "test.example.local/gg/dd?aa=11&rr=22"
HTTP/1.1 200 OK

3. Caddy version:

4. How I installed and ran Caddy:
a. System environment:
docker compose.
b. Command:
caddy run --config /etc/caddy/Caddyfile --adapter caddyfile
c. Service/unit/compose file:
