Function proxyProtoConfig

caddytest/integration/proxyprotocol_test.go:324–366

proxyProtoConfig builds a Caddy JSON configuration that: - listens on listenPort for inbound HTTP requests - proxies them to backendAddr with PROXY protocol ppVersion ("v1"/"v2") - uses the given transport versions (e.g. ["1.1"] or ["h2c"])

(listenPort int, backendAddr, ppVersion string, transportVersions []string)
