I have a domain example.com that is being host on webfaction. However i would like to redirect its subdomain (e.g sub.example.com) to one of my AWS instance which has public DNS of:
https://ec2-xx-xxx-xxx-xxx.ap-southeast-1.compute.amazonaws.com:8083 (please note the port number).
This instance is then assigned with elastic IP address.
So far, the solution that i tried is:
Using CNAME redirection, however it does not work because of this: https://forums.aws.amazon.com/thread.jspa?threadID=55995
Then i proceed to use the old fashion .htaccess:
Redirect permanent / http://ec2-xx-xx-x-xxx.compute-1.amazonaws.com order deny,allow
However, i want to keep the sub.example.com on the address bar instead of changing it AWS public dns.
Does anyone know what is the best way to solve this? Thanks
