摘要

Caching objects in Internet environment is aimed to reduce bandwidth consumption and increase the response time of system in term of user perception.Researcher believes that theudperformance of web cache is dependent on user access behavior.Therefore, many studies on workload of the internet web cache have been conducted.However, in the web cache environment,udthe study in inter-reference time of the successive requests is rarely.This paper tries to explore the characteristic of workload of the internet web cache, especially on the inter reference time (IRT).Based on the correlation test and trend analysis, it can be concluded that IRT is reasonable to be applied as a metric of webudcache replacement policy.
