Amazon CloudFront setup with custom domain name

Question

I have an application which serves assets under the following URL:

https://example.com/assets/...

Now I want to use Amazon CloudFront to serve these assets with the URL

https://cdn.example.com/assets/...

---

The things I have done:

1. I created a new distribution with the origin of cdn.example.com
2. I added a CNAME DNS record pointing cdn.example.com to example.com

---

Now I feel like that configuration does not serve the assets via CloudFront. Instead if I request my CloudFront Domain Name, lets say dpw02sdffky7p.cloudfront.net , I get redirected to example.com . So it feels like my assets are still being served from my server, just with some redirects in between.

Am I right? What would be the correct configuration to achieve my goal?

Answer 1

while creating cname record in route53, Alias should be given as yes for endpoints like cloudfront, it will resolve the redirection in server side itself.
