A Proxy Load Reduction Technique to Improve Web performance

Abstract

The rapid growth of World Wide Web has caused serious performance degradation on the Internet. Web traffic has increased tremendously since the beginnings of the 1990s and overloading conditions of proxy servers occur repeatedly on Internet. Many people have started calling the WWW the World Wide Wait. In order to solve the problem of overloading on proxy servers, a new approach by extending cache memory close to the proxy server which stores a list of the most popular Websites, called the hot-site list, to reduce the unnecessary requests reaching to proxy server caches has been proposed in this work. These unnecessary client requests called the miss requests which cause the proxy caches to store copies of the requested information but the copies will not be accessed again. If the requests are not available in the hot-site list, then the forward proxy will forward the request to the original server. This is made possible only when the browsers are informed about the list of popular Websites. In this research, the extended cache memory on server side is used which may be in the form of hard disk to reduce load and response time on the proxy server which in turn improves the performance of Web. This extended cache memory placed at proxy server side. This research also focused on the working of the existing Web cache proxy server.
