Abstract

In this paper, we use the Pollock’s robust design method in order to measure the ability of five well known Internet search services, namely Altavista, Google, Lycos, MSN and Yahoo! (in alphabetical order), in terms of maintaining fresh and up-to-date results in their cache directories. This paper demonstrates the first Internet-based measuremets regarding the sampling of the cached results along with their initial assesment. For conducting the sampling occassions we used a client-server communication mechanism (XMLHttpRequest), which is based on the Asynchronous Javascript and XML technology (AJAX).
