Web Cache Replacement Strategy Based on Reference Degree

Currently, most of the existing web cache replacement strategies are based on temporal locality, frequency distribution and size distribution while spatial locality gets less attention. This paper proposed a reference model to evaluate the spatial locality of web object accessing, and used the reference model as the basis of a new cache replacement strategy -- GDSR, Greedy-Dual-Size Reference. GDSR improved the performance of cache replacement strategy, providing a new direction and idea for the design of web cache replacement strategies.
