Installation and Configuration of Apache Traffic Server under Ubuntu

Global data networking has become part of everyday life: internet users request billions of documents and terabytes of data, on a daily basis, to and from all parts of the world. Information is free, abundant, and accessible. Unfortunately, global data networking can also be a nightmare for IT professionals as they struggle with overloaded servers and congested networks. It can be challenging to consistently and reliably accommodate society’s growing data demands.

Traffic Server is a high-performance web proxy cache that improves network efficiency and performance by caching frequently-accessed information at the edge of the network. This brings content physically closer to end users, while enabling faster delivery and reduced bandwidth use. Traffic Server is designed to improve content delivery for enterprises, Internet service providers (ISPs), backbone providers, and large intranets by maximizing existing and available bandwidth.
