The growth of the internet users has been exponential over a period of time. This has led to the increased use of web for sharing content and services. Huge load on the bandwidth of the internet and the large number of requests for the content and services present in the website is due to the increased use of web for variety of purposes. This has restricted the ability of the internet to send the required data to the users in a time bound manner.
