Question Plesk special DNS redirect entry possible?

[speedbird]

Hello dear Pleskians,

I have the following situation:

Server A -> running Plesk and being hidden primary DNS for all hostings
Server B -> running a server application

Now, on Server A, for a specific domain, I created a subdomain and changed the A record so that it points to the IP of Server B. Now when typing xx.servera.com one gets redirected to Server B.

But that's only part of what I want. What I need is that the subdomain is still accessible via xx.servera.com but every other request is sent to Server B which only hosts the server application, not the website, which shall reside on Server A.

Is that even possible by DNS or do I have to take a different approach. Any ideas?

Summary:

xx.servera.com should resolve to Server B BUT all web access requests should still be served by Server A running plesk.

Thanks!
