Beschreibung: We consider the problem of decreasing users' waiting time in accessig WWW objects. The traditional soulutin uses the proxy server to cache remote objects. In this study, we propose a pre-fetch mechanism which uses the technique of mining association rules to improve the cache hit ratio of the Squid proxy server. According to the requests made by proxy server users , this mechanism can pre-fetch WWW objects that are probably accessed next and store them in the local cache of the proxy server. The user can then fetch the next objects in a short time. To verify the feasibility of this pre-fetch mechanism, we use user accesslogs in the proxy server to test the performance of our mechanism. Experimental results show an improvement of about 30% of the cache hit ratio, and learning more association rules can even increase the cache hit ratio about 47%. ; 成功大學, 台南市
