Address

The hostname or address Caddy will respond to. Add multiple to share one configuration. Use *.example.com for wildcards (requires DNS-01 below).

HTTPS & TLS

Caddy issues and renews certificates automatically.

Site-wide

Response headers

Set, add, remove, or default headers on every response from this site.

Access control

Path routes

Match specific paths and forward each to a different handler. Routes are evaluated by specificity, not order. Caddy picks the most specific match automatically.
