Abstract: A plurality of forwarding servers is communicatively coupled to a plurality of sending systems via a network. A first forwarding server associated with a first geographical region includes an interface that receives a first request for a resource from a first sending system via the network. A determination logic determines whether one or more requests that precede the first request are received from the first sending system at a second forwarding server associated with a second geographical region. A causation logic causes the first request to be forwarded to a second endpoint associated with the second geographical region rather than a first endpoint associated with the first geographical region at least partly based on an inference that the first sending system is located in the second geographical region.

Abstract: Techniques are described herein that are capable of forwarding a current request based on, at least in part, previous request(s). For instance, the current request may be received at a first forwarding server from a sending server via a network. The first forwarding server may determine that a second forwarding server is associated with (e.g., receives, causes to be forwarded, or responds to) previous request(s) from the sending system. The first forwarding server may cause the current request to be forwarded to an endpoint based on, at least in part, the previous request(s) being associated with the second forwarding server. For instance, the first forwarding server may cause the current request to be forwarded to the endpoint based on, at least in part, the second forwarding server forwarding the previous request(s) to the endpoint.

Abstract: Embodiments are directed to establishing caches that provide authoritative domain name system (DNS) answers to DNS requests. In one scenario, a computer system establishes a cache that stores authoritative DNS answers to DNS queries. The cache corresponds to a specified DNS zone that includes authoritative DNS answers for a subset of DNS queries. The cache is configured to store the authoritative DNS answers for at least a specified period of time during which the authoritative DNS answers are updatable. The cache then receives an update indicating that at least one cached DNS answer is out-of-date and the computer system purges the out-of-date DNS answer from the cache, ensuring that the cache continually provides authoritative DNS answers for DNS queries assigned to the specified DNS zone.
