Web proxy cache can solve the problems of user access delay and network congestion to a certain extent. The cache replacement strategy of web proxy cache directly affects the hit rate of cache, thereby affecting the effect of network request response. To solve this problem, using a fixed-size sliding window to extract multiple features of Web log data, and using a Gaussian mixture model for cluster analysis of Web log data, predicting that the Web object may be accessed again within the sliding window time, combining the least Using (LRU) algorithm, a new cache replacement strategy of web proxy server based on Gaussian mixture model is proposed. The results show that compared with the traditional cache replacement strategies such as LRU, LFU, FIFO, GDSF, the proposed strategy effectively improves the request hit rate and byte hit rate of web proxy cache.
