System and method for using a variable analysis window to produce statistics on downloadable media

摘要

The present invention teaches a method for determining an accurate measure of unique download sessions in an environment where IP addresses are shared among multiple devices. According to a first preferred embodiment, the system of the present invention may analyze requested server log data to determine the number of unique client devices sharing the same IP addresses. The system may then dynamically adjust the length of lookback windows for each unique device based on observed download behavior and the number of user agents associated with each overlapping IP address.
