# Add a domain with automatic TLS (Let's Encrypt/ZeroSSL) and www redirect
client.add_domain_with_auto_tls(
    domain="example.org",
    target="nginx",
    target_port=80,
    redirect_mode="domain_to_www",  # Redirects example.org to www.example.org
    enable_security_headers=True,    # Adds security headers
    enable_hsts=True                 # Enables HSTS
)

# Add a domain with www to non-www redirect
client.add_domain_with_auto_tls(
    domain="www.example.net",
    target="192.168.10.101",
    target_port=80,
    redirect_mode="www_to_domain"  # Redirects www.example.net to example.net
)

# Add a domain with custom TLS certificates using PEM data
with open('cert.pem', 'r') as f:
    certificate = f.read()
with open('key.pem', 'r') as f:
    private_key = f.read()

client.add_domain_with_tls(
    domain="example.net",
    target="192.168.10.101",
    target_port=80,
    certificate=certificate,
