create a subdomain for a virtuoso installation

Question

We have a Virtuoso installation on an AWS VM, working on default port 8890, that we would like to create a subdomain, e.g., rdf.example.com:8890. The problem is that the guy that is responsible for the subdomains created a record on the service we use (don't know which), but it is not working.
Is there something that needs to be done in order for virtuoso to work under a subdomain?

I used the AWS's Route53, with no luck as well.

Answer 1

Seems you want to setup a multi-homing setup for hosting multiple subdomains on the same Virtuoso instance, which Virtuoso supports as in the link above.

Failing that I would suggest posting your question on the OpenLink Community Forum, to get more expert responses ...
