METHOD FOR CONTENT CACHING USING CACHE SERVER AND BROWSER CACHE, AND CACHE SERVER THEREOF

摘要

PURPOSE: A method for content caching using a cache server and a browser cache, and a cache server thereof are provided to use updated contents through data communication between clients by storing the updated contents having validity after grouping plural client browser cache. CONSTITUTION: If a first client(110-1) requests contents, a cache server(130) transmits contents. The first client stores the contents as a browser cache(120-1), and the cache server classifies the 2nd to nth browser cache(120-2 to 120-n) including the first browser cache into browser cache group. The cache server inspects the validity of contents of the 1st browser cache periodically. Unless the contents have validity, the cache server requests the updated contents from the content server.
