Route53: 2 A records to 1 load balancer

votes

I have two hosted zones in Route53:

  1. domain1.com > A record > Simple routing policy > my_load_balancer

  2. domain2.com > A record > Simple routing policy > my_load_balancer

my_load_balancer is the same for both A records. I'd like to use the same application load balancer (my_load_balancer) to forward the requests to domain1.com to target1, and domain2.com requests to target2 (I have created the rules on the load balancer already). However, I am getting "request timed out" for domain2 and cannot figure out the cause. It looks like Route53 does not resolve for the second domain pointing to the same load balancer

Is 1 load balancer for 2 targets/domains (hosted on 2 different instances) possible at all (I read somewhere that it is possible)? What is missing? Please, advise

In case someone else comes across the same. The above (and below) setup works fine. The basic settings are as follows:

Route53:
Hosted zone domain1.com: A record > my_app_load_balancer
Hosted zone domain2.com: A record > my_app_load_balancer
(where my_app_load_balancer is the same load balancer)

On the load balancer:
Rule 1: if host is domain1.com then forward to the target for domain1.com
Default rule: if host is domain2.com then forward to the target for domain2.com

In my case this was not working due to the DNS cache issues on my machine. I was testing from Windows, so to make it work I did >ipconfig /flushdns
