Workflow for Setting Noindex,Nofollow Headers with a Subdomain Pointing to CloudFront to s3 To set Noindex,Nofollow header to all object in s3.

Configure S3 Bucket: Create or select an S3 bucket to store your content. Ensure the bucket is private, granting access only to CloudFront

Set Up Subdomain: Configure your DNS settings to create a subdomain (e.g., cdn.example.com). Point the subdomain to the CloudFront distribution using a CNAME record.

Create or Configure CloudFront Distribution:

Set the S3 bucket as the origin for the CloudFront distribution. Link the CloudFront distribution to the subdomain (e.g., cdn.example.com). Define cache behaviors as needed to control content delivery.

Apply Noindex, Nofollow Headers:

In the CloudFront distribution settings, create or modify a custom response header policy. Add the X-Robots-Tag header with the value noindex, nofollow to the policy. Apply this header policy to the relevant cache behaviors or globally across all objects served by CloudFront.

Update CloudFront Cache (Optional): Invalidate the CloudFront cache if necessary to ensure the Noindex, Nofollow headers are applied to all cached objects. Test the Configuration:

Access content via the subdomain (e.g., cdn.example.com) and inspect the HTTP headers to confirm the X-Robots-Tag is set to noindex, nofollow

Monitor and Maintain: Regularly monitor the CloudFront distribution and subdomain to ensure headers are applied as expected. Maintain the security settings of the S3 bucket to restrict direct access, allowing only CloudFront. genrate image for this
