Caddy is a production-grade, extensible web server platform written in Go. It automatically manages HTTPS certificates (via ACME/ZeroSSL) and provides a rich set of HTTP middleware including reverse proxy, file serving, authentication, compression, and headers manipulation. The architecture is modular: all features are registered as Caddy modules following a consistent lifecycle (Provision/Validate/Cleanup) and configured via a JSON config or the Caddyfile adapter. Key entry points are the CLI (caddy run, caddy start, etc.) and the admin API for runtime config changes. Primary data flows involve incoming HTTP requests being processed by a middleware chain of matchers and handlers, with TLS termination handled by the TLS app. External dependencies include certmagic for certificate management, zap for structured logging, Prometheus for metrics, and OpenTelemetry for tracing. The codebase is actively maintained with extensive test coverage and fuzz testing.
This is a comprehensive V2Ray installation and management script written in Bash. It provides a one-click installer (install.sh) and a management CLI (v2ray.sh) for deploying and operating V2Ray proxy servers on Linux (Ubuntu/Debian/CentOS). The script automates V2Ray core installation, configuration generation for multiple protocols (VMess, VLESS, Trojan, Shadowsocks, Socks, Dokodemo-Door), TLS certificate management via Caddy, dynamic port allocation, BBR enablement, and DNS configuration. It uses a modular architecture with separate source files for each functional area (core.sh for protocol logic, caddy.sh for TLS, dns.sh, bbr.sh, systemd.sh for service management, download.sh for fetching binaries, log.sh, old.sh for migration). The script manages multiple simultaneous configurations via JSON files in /etc/v2ray/conf/ and uses V2Ray's API for hot-reloading. It supports both interactive menu-driven operation and direct command-line arguments for automation.
