Pre-Fetching in Web Cache Cluster

Exponential growth of Internet results in increased network bandwidth usage. Since it is expensive to increase the bandwidth capacity of the network, alternate software technologies are developed. Web caching and pre-fetching techniques are recognized as the most important techniques for web latency reduction. A user requesting content served by the cache is able to avoid the delays inherent in the web such as slow servers and congested networks. Pre-fetching techniques are used for fetching the anticipated web pages earlier. Pre-fetching technique has been incorporated in web cache cluster for reducing latency and accessing web pages without much bandwidth consumption.
