Introduction

Apache Traffic Server is a highly scalable caching proxy server capable of handling large volumes of concurrent requests while maintaining a very low latency. Compared to other popular proxy servers, such as Varnish or Squid, it usually consumes less memory and responds faster. It is also designed to make the most of modern multi-core processors. Depending on your requirements, you can use it as a reverse proxy or as a forward proxy.

This tutorial will cover how to install Apache Traffic Server on Ubuntu 14.04 and configure it to behave as a caching reverse proxy.

Prerequisites

To follow this tutorial, you will need:

• One Ubuntu 14.04 Droplet

Introduction

The Apache web server is the most popular way of serving web content on the internet. It accounts for more than half of all active websites on the internet and is extremely powerful and flexible.

Apache breaks its functionality and components into individual units that can be customized and configured independently. The basic unit that describes an individual site or domain is called a virtual host.

These designations allow the administrator to use one server to host multiple domains or sites off of a single interface or IP by using a matching mechanism. This is relevant to anyone looking to host more than one site off of a single VPS.

Each domain that is configured will direct the visitor to a specific directory holding that site’s information, never indicating that the same server is also responsible for other sites. This scheme is expandable without any software limit as long as your server can handle the load.

In this guide, we will walk you through how to set up Apache virtual hosts on an Ubuntu 14.04 VPS. During this process, you’ll learn how to serve different content to different visitors depending on which domains they are requesting.
