摘要
Provided are a cache optimization method, a cache and a cache optimization system. The cache optimization method comprises: a cache node receiving a plurality of service requests from a terminal for a first uniform resource locator (URL), respectively receiving a plurality of first response messages from a content source based on the plurality of service requests, and respectively determining the first signature values of contents contained in the plurality of first response messages when all of the plurality of first response messages do not carry a cache control header field, or the carried cache control header field indicates no caching; and the cache node comparing the plurality of first signature values, and if they are the same, caching the contents contained in the first response messages and the first URL, and if they are not the same, not caching the contents contained in the first response messages. The cache optimization method, the cache and the cache optimization system in the embodiments of the present invention can determine the cache contents cached in a local caching device based on the signature values of the requested service contents, thereby reducing the bandwidth and enhancing the terminal service experience.
