摘要： Web集群的caching优化对提高系统性能起重要作用。从基于caching优化的角度出发，以事务为一个完整的划分单元，形成Web集群的缓存集。提出了基于事务缓存优化策略，在此基础上给出了一种基于cache的负载均衡算法。

Abstract: Cache optimizing of Web cluster can lead the enormous improvement to the whole Web cluster system. Based on cache optimizing, regarding transaction a full divisiory unit, constituting caching sets of Web cluster. An cache optimizing policy based on task is introduced.Then, a load-balancing algorithm based on cache is introduced.
