US Patent 9647957 Throttling usage of resources

A computing device provides a first server. The first server receives a primary request associated with a client. In response to receiving the primary request, the first server processes the primary request to generate a response message. As part of processing the primary request, the first server sends a secondary request to a second server after a delay period expires. The second server accesses a resource as part of processing of the secondary request. The duration of the delay period depends at least in part on a recent latency level of the client with regard to the resource. In this way, the first server throttles access to the resource.
