Abstract
A method controlling near caches in a distributed cache environment including distributed cache servers is provided. The method includes steps of: a specific distributed cache server among the distributed cache servers, if a request signal for original cache data is obtained from a client node, transmitting replicated cache data for the original cache data to the client node, to support the client node to store and refer to the replicated cache data in its corresponding near cache storage part, and managing a reference map with a correspondence between the client node referring to the replicated cache data, and the original cache data; and if the original cache data is changed, checking the number of the client nodes referring to the replicated cache data by referring to the reference map, and invalidating the replicated cache data according to the number of the checked client nodes.
