Abstract: The exponential growth of internet has resulted in an estimated 2.2 billion users accessing more than 600 million websites with millions of terra bytes of data. Internet users increasingly demand high bandwidth content such as HD and 3D video. This strains the access networks being unable to expand at the same rate as the demand mostly due to financial constraints than technical constraints. Techniques such as web caching and web pre-fetching were developed in order to reduce the user perceived latency when accessing popular content. Content Delivery Networks (CDNs) such as Akamai provide the advantage of better performance and high availability through a network of distributed servers hosting a large portion of the internet content by offloading traffic directly served from the content provider's origin infrastructure. In this paper, the authors attempt to combine these three techniques namely; prefetching, caching and the CDN approach to further reduce the user perceived delay in accessing the web. Through a real implementation the performance of the proposed system is compared with existing architectures.
