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:
  caddy

  example.com {
      reverse_proxy localhost:3000
  }

3. PHP (FastCGI)

• Directives: Use

  php_fastcgi

  preset.
  caddy

  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.
  caddy

  header {
      Strict-Transport-Security "max-age=31536000;"
      X-Content-Type-Options "nosniff"
  }
