Abstract

Along with the recent development of CDN, the web proxy caching has been adopted in many main techniques. In this paper, by contrast to the regular removal policies based on single proxy server, we prefer to evaluate a retrieved web object based on the metrics gathered from multiply proxy caches regionally. We particularly introduce a concept called post-removal analysis, which is used in measuring the value of the removed objects. Finally, we use the real proxy cache Squid to implement our proposal and modify the cache benchmarking tool Web Polygraph to test this cooperative prototype. The test results prove that the proposed scheme can optimize the content distribution and bring noticeable performance improvement.
