because the server has a new IP address. So we need to trigger a name
resolution to know this new IP.
When using resolvers, the server name can either be a hostname, or s SRV label.
HAProxy considers anything that starts with an underscore a SRV label.
If a SRV label is specified, then the corresponding SRV records will be
retrieved from the DNS server, and the provided hostnames will be used. The
SRV label will be checked periodically, and if any server are added or removed,
haproxy will automatically do the same.
A few things important to notice:
- all the name servers are queried in the mean time. HAProxy will process the
first valid response.
