It’s been a while since I started using caddy v2 in production. Therefore I would like to show some caddy configuration examples that I also use by myself.

HTTP3 in Caddy v2

In the last caddy post I mentioned how to setup HTTP3, however the syntax has changed slightly.

{
  servers :443 {
    protocol {
      experimental_http3
    }
  }
}

Reverse proxy

Simple reverse proxy (to a specific port)

1
2
3

matrix.rmsol.de {
  reverse_proxy localhost:8008
}

File server

Serving a static page (html/css). In that case with gzip and extended Cache-Control.

rmsol.de {
  root * /var/www/rmsol.de
  encode gzip
  header Cache-Control max=age=3600
  file_server
}

PHP website

Serving a PHP website.

ip-whois.de {
  root * /var/www/ip-whois.de
  file_server
  php_fastcgi unix//var/run/php/php7.4-fpm.sock
}

Nextcloud

nextcloud.rmsol.de {
  root * /var/www/nc
  file_server

  php_fastcgi unix//var/run/php/php7.4-fpm.sock
  header {
    Strict-Transport-Security max-age=31536000; # enable HSTS
  }

  redir /.well-known/carddav /remote.php/dav 301
  redir /.well-known/caldav /remote.php/dav 301

  @forbidden {
    path /.htaccess
    path /data/*
    path /config/*
    path /db_structure
    path /.xml
    path /README
    path /3rdparty/*
    path /lib/*
    path /templates/*
    path /occ
    path /console.php
  }

  respond @forbidden 404
}
