Required Caddyfile Changes

1. Add a log block to your Caddyfile

Add the logging configuration to a snippet or to each individual site block:

(hsts) {
    log {
        output file /var/log/caddy/access.log {
            roll_size 100mb
            roll_keep 10
        }
        format json
    }
    header {
        Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"
        X-Content-Type-Options "nosniff"
        Referrer-Policy "strict-origin-when-cross-origin"
        Permissions-Policy "geolocation=(), microphone=(), camera=()"
        -Server
    }
}

some.dns.com {
    import hsts
    reverse_proxy 192.168.71.6:1378
}

2. Create the log file with correct permissions (BEFORE reloading!)

mkdir -p /var/log/caddy
touch /var/log/caddy/access.log
chown caddy:caddy /var/log/caddy/access.log

3. Reload Caddy

systemctl reload caddy
