My problem

I'm trying to 301 redirect myS3 hosted domain-a.com to domain-b.com in my SSL-secured AWS Cloudfront setup. I cannot figure out how to achieve this. Instead both domains now serve the Cloudfront/S3 Bucket content.

My use case

Before switching to Cloudfront I used to handle redirects with S3's static website hosting options by redirecting the secondary domain bucket to the primary domain bucket.

In order to secure my S3-hosted static site with SSL certificates I made the switch to Cloudfront.

SSL certificates work fine, but because now both domains point to the cloudfront distribution (see screenshots below) I can access the same content on both domains. This does not only lead to duplicate content but also confuses users and is not really the best UX.

Route 53 and Cloudfront config for both domains

• Route 53 points to a single Cloudfront distribution for both domain-a.com and domain-b.com


• Cloudfront points to the domain-b.com S3 bucket

How can I redirect domain-a.com to domain-b.com so as to only have one primary domain which my users see and use? Can this be achieved through Route 53 DNS settings or do I have to edit my Cloudfront configuration?

Create a separate bucket for domain-a.com, configure that in your CloudFront and apply the redirect rules to point it to domain-b.com.

Check the picture below on how to set the redirect.

Hope it helps.
