1. Caddy version (caddy version
): v2.4.6
a. System environment:
Ubuntu 20.04.4
b. Command:
./caddy run --config /cms/setupHost/configs/etc/caddy/Caddyfile
c. Service/unit/compose file: N/A
d. My complete Caddyfile or JSON config:
header x-bcms-web-rt {http.request.duration}
reverse_proxy http://127.0.0.1:8000 {
header_down x-bcms-web-app-rt {http.reverse_proxy.upstream.latency}
}
3. The problem I’m having:
I’m trying to return the placeholders {http.request.duration} and {http.reverse_proxy.upstream.latency} in http headers, but I’d like these to be returned without the time formatting suffix (µs, ns, ms, etc).
Instead of 655.947µs
, I would prefer 0.655947
which is millisecond resolution, without the ms
string at the end.
I would like this so that my upstream logging doesn’t need to do any conversions, as it appears the special µ
character gets mangled by various upstreams, including my CDN provider (Cloudflare).
curl -I http://127.0.0.1/dashboard-dev/
X-Bcms-Web-App-Rt: 655.947µs
X-Bcms-Web-Rt: 65.29µs
