Caddy Modern Config

When to use this skill

• Configuring Caddy as a web server or reverse proxy.

• Setting up local HTTPS.

• Deploying PHP/Python apps with Caddy.

1. Caddyfile Basics

• Syntax: domain { directives } .

• Auto-HTTPS: Enabled by default for any host that looks like a domain.

2. Reverse Proxy

• Python/Node: example.com { reverse_proxy localhost:3000 }

3. PHP (FastCGI)

• Directives: Use php_fastcgi preset. example.com { root * /var/www/site/public php_fastcgi unix//run/php/php8.3-fpm.sock file_server }

4. Security

• Headers: Add basic security headers easily. header { Strict-Transport-Security "max-age=31536000;" X-Content-Type-Options "nosniff" }
