Fungsi respons penampil berikut menambahkan beberapa header HTTP terkait keamanan umum ke respons. Untuk informasi lebih lanjut, lihat halaman berikut di situs web MDN Web Docs:

• Keamanan Transportasi Ketat

• Kebijakan Keamanan Konten

• X-Konten-Tipe-Pilihan

• X-Frame-Opsi

• Perlindungan X-XSS

Lihat contoh ini di GitHub.

JavaScript runtime 2.0

async function handler(event) {
    const response = event.response;
    const headers = response.headers;

    // Set HTTP security headers
    // Since JavaScript doesn't allow for hyphens in variable names, we use the dict["key"] notation 
    headers['strict-transport-security'] = { value: 'max-age=63072000; includeSubdomains; preload'}; 
    headers['content-security-policy'] = { value: "default-src 'none'; img-src 'self'; script-src 'self'; style-src 'self'; object-src 'none'; frame-ancestors 'none'"}; 
    headers['x-content-type-options'] = { value: 'nosniff'}; 
    headers['x-frame-options'] = {value: 'DENY'}; 
    headers['x-xss-protection'] = {value: '1; mode=block'};
    headers['referrer-policy'] = {value: 'same-origin'};
    
    // Return the response to viewers 
    return response;
}
