Abstract
Time to live ('TTL') values are determined based on one or more factors. The TTL values may be included in responses to requests for resources, thereby affecting the frequency of subsequent requests. This dynamic determination of TTL values may provide resilience to system load, for example by using longer TTL values when the system is under greater load in order to reduce the rate at which subsequent requests are received. A dynamic TTL service may calculate a TTL value based on one or more factors, such as overall system load, resource load, hardware load, and/or software load. In various embodiments, a dynamic TTL service may act natively within a service, within a system framework, as a proxy, as a cluster, and/or as a broker.
