Example

// Using an existing managed response headers policy
declare const bucketOrigin: origins.S3Origin;
new cloudfront.Distribution(this, 'myDistManagedPolicy', {
  defaultBehavior: {
    origin: bucketOrigin,
    responseHeadersPolicy: cloudfront.ResponseHeadersPolicy.CORS_ALLOW_ALL_ORIGINS,
  },
});

// Creating a custom response headers policy -- all parameters optional
const myResponseHeadersPolicy = new cloudfront.ResponseHeadersPolicy(this, 'ResponseHeadersPolicy', {
  responseHeadersPolicyName: 'MyPolicy',
  comment: 'A default policy',
  corsBehavior: {
    accessControlAllowCredentials: false,
    accessControlAllowHeaders: ['X-Custom-Header-1', 'X-Custom-Header-2'],
    accessControlAllowMethods: ['GET', 'POST'],
    accessControlAllowOrigins: ['*'],
    accessControlExposeHeaders: ['X-Custom-Header-1', 'X-Custom-Header-2'],
    accessControlMaxAge: Duration.seconds(600),
    originOverride: true,
  },
  customHeadersBehavior: {
    customHeaders: [
      { header: 'X-Amz-Date', value: 'some-value', override: true },
      { header: 'X-Amz-Security-Token', value: 'some-value', override: false },
    ],
  },
  securityHeadersBehavior: {
    contentSecurityPolicy: { contentSecurityPolicy: 'default-src https:;', override: true },
    contentTypeOptions: { override: true },
    frameOptions: { frameOption: cloudfront.HeadersFrameOption.DENY, override: true },
    referrerPolicy: { referrerPolicy: cloudfront.HeadersReferrerPolicy.NO_REFERRER, override: true },
    strictTransportSecurity: { accessControlMaxAge: Duration.seconds(600), includeSubdomains: true, override: true },
    xssProtection: { protection: true, modeBlock: true, reportUri: 'https://example.com/csp-report', override: true },
  },
});

  defaultBehavior: {
    origin: bucketOrigin,
    responseHeadersPolicy: myResponseHeadersPolicy,
  },
});
