    Abstract: System and method for estimated update timing of cached data. A client-side cache manager updates the active TTL for each cached data entity based on a state value and covariance values indicating the level of certainty in the state value. The state value comprises the average time between updates to server side data. Each time a particular data entity is requested from the server, the state value is updated to reflect the current estimate and the covariance value is updated to reflect the corresponding certainty Kalman filtering techniques are used which are different from standard Kalman filtering in that the same state being estimated dictates when “measurements” can be made. Additionally, the state being estimated is not directly observable; the only thing that is observable is whether the data has changed since the last time a request was made. Consequently, additional operations may be performed to improve the estimation.
