proxy_pass + 5 lines of proxy_set_header collapse to a single reverse_proxy. Host, X-Forwarded-For, and WebSockets are handled automatically.

proxy_pass http://127.0.0.1:3000;
proxy_set_header Host $host;
proxy_set_header Upgrade $http_upgrade;

➔

reverse_proxy 127.0.0.1:3000

ssl_certificate directives are stripped. Caddy automatically issues, renews, and configures TLS via Let's Encrypt / ZeroSSL.

ssl_certificate /etc/letsencrypt/...;
ssl_certificate_key /etc/letsencrypt/...;

➔

# Automatic HTTPS (Zero config)

try_files + fastcgi_pass and param scripts collapse into php_fastcgi and file_server.

try_files $uri $uri/ /index.php?$args;
fastcgi_pass unix:/run/php.sock;

➔

php_fastcgi unix//run/php.sock
file_server

Complex regex RewriteRules translate directly into human-readable redir statements.

RewriteRule ^blog/(.*)$ /posts/$1 [R=301,L]

➔

redir /blog/* /posts/{1} permanent
