Intelligent proxy techniques in plasma physics laboratories

In plasma physics laboratories, people are making full use of the Web to obtain the latest information. In this paper, we study intelligent proxy techniques for people who have similar interests and use a common division proxy to access the Web. Based on the analysis of web proxy workload characterization, we propose a new replacement algorithm for proxy cache. Trace-driven simulation is used to evaluate several algorithms. The proxy can predict which Web files will be needed in the near future and download some of them before they are requested by users. The optimized prefetching threshold is dynamically modified based on the measured network performance
