Abstract

We develop an analytical model of the web proxy cache and obtain the hit ratio in terms of the incoming requests rate, replacement distribution and document’s modification rate. We choose a queuing network to evaluate the decrease of the response time. Numerical results show that securing a perfect coherency leads to performance degradation which could be significant in extreme cases.
