Web Caching System by Using Hybrid Replacement Cache Algorithm (HRC)

Abstract

Web is fundamentally a very simple idea. Web server that accept request from web Clients for pieces of information called web objects. When a user accesses a web page, the request typically goes out to the Internet to the server on which the page resides. The page content is then returned back across the Internet to the user’s workstation. Web Caching works by storing the content of requested web pages on a dedicated caching server inside the network. The system would apply Hybrid Replacement Cache(HRC) Algorithm for caching another web pages when the cache is full. When the client makes a request, the browser is then checked whether it is in server cache or not and request information’s frequency and last access time is recorded in the database. If it is in its sever cache after checking, the web information is displayed on the browser. Next step is considering how to cache the web objects and compare the size of the requested page and existing cache size whether the web object has to be saved in server cache or not. Applying this algorithm, this system reduce network traffic and user latency.
