Hello everybody. I'm trying to figure out if it is possible to make pdns (or dnsdist) to return a different answer according to the availability of a service.
Suppose we have: - server A with IP: XXX.XXX.XXX.XXX - server B with IP: YYY.YYY.YYY.YYY Server A and B are two web servers which are configured to answer to a given http GET like http://myservice.net. They are both configured in the same way and are independent. I would like the DNS query to return XXX.XXX.XXX.XXX as long as the server A is working (returns 200 to the GET) or return YYY.YYY.YYY.YYY when server A is not working. In other words, I would like to have two records A for myservice.net with a somehow "intelligent" behavior and not a simple round-robin. Can you suggest me how to achieve this, if it's possible? Thanks a lot Riccardo
