caddy-security HTTP integration Caddyfile configuration. Use when creating, reviewing, or modifying route-level authenticate and authorize directives, portal and protected route separation, matcher forms, same-host or split-host auth wiring, auth URL routing and alignment, auth-path collisions such as upstream /auth routes, dedicated auth hosts with root-mounted portals, portal-owned path prefixes to avoid, or unnecessary global Caddy directive-order overrides.
