如何在 Route53 中从非 WWW 路由到 WWW？

Question

I've seen all the solutions for this kind of questions, but they are all related with S3 bucket solutions. These solutions does not fit my issue, because I don't see how S3 bucket is related with it.

Anyway, I have a domain name www.example.com . I use an A Record to route it to my ALB. Works fine. By now, I had some configuration for example.com (routed via A Record to ALB). But this practice is considered bad because SEO considers these 2 domains as 2 different pages.

So What I need is to redirect(?) example.com to www.example.com .

I tried configure PTR Routing type on example.com to www.example.com but that's just doesn't work. When I do so I get "DNS_PROBE_FINISHED_NXDOMAIN".

What is the correct way to do so?

Answer 1

For this, you can also create a CNAME record with host as www and value is your LB or IP.
