Send additional records in DNS response
- by Joel
Is is possible to send one or more additional records with a DNS response?
For example, can a request for the A record of www.example.com result in a response containing the A record for www.example.com as well as the A record for www2.example.com?
Is this compliant with the standard? Will it even help? ie. Will the typical client cache the additional record so that when it needs it in the near future, it won't result in another round-trip to the DNS server?
