caddy-0.9.9

Bug Fixes

• Route upsert no longer fails with duplicate @id error — PUT /id/<id> momentarily indexes both the old and new route entries before removing the old one, causing Caddy to reject the update with duplicate ID found at routes/1 and routes/2. Fixed by switching to DELETE + POST, which removes the existing route atomically before re-adding the updated one.
• X-Real-IP / X-Forwarded-For headers now carry the real client IP — the {client_ip} Caddyfile shorthand is not a raw JSON placeholder; {http.vars.client_ip} is the correct form in the admin-API JSON config. Changed injectRealIP to use {http.vars.client_ip} so the headers expand to the trusted-proxy-aware client IP instead of the literal string {client_ip}.

Helm chart: 0.9.9

• Placeholder :80 / :443 blocks now carry a respond /healthz 200 route — empty server blocks leave the routes field as null in Caddy's JSON config. When k8s_ingress tries to POST a new route to a null array, Caddy returns cannot unmarshal object into RouteList. The placeholder routes initialise the array so dynamic route injection works on a fresh pod.
