DOMAIN NAME CACHE CONTROL
First Claim
Patent Images
1. A system to control caching duration of mappings between domain names to IP addresses, comprising:
- a generation component that generates a nonce; and
a constructor component that appends the nonce to a domain name to form a nonce-bearing name and force propagation of IP address lookup to an authoritative server.

Abstract
Domain name caching is controlled by adding a nonce to a domain name to force propagation of lookup to an authoritative server or service. Desired caching behavior is dictated by controlling when a new and unique nonce-bearing name is created. For example, caching can be completely eliminated by generating a new nonce-bearing name for every request. While a nonce can simply correspond to a random or pseudo random value, it can also be time based. Furthermore, nonces can be phase or time shifted to limit authoritative server load as well as improve response time.
