"Varnish Cache How-to" is a practical, hands-on guide that will take you from beginner to advanced, improving your website speed and dropping the bounce and page abandonment rates of your website. With easy-to-follow recipes, this book will help you take advantage of caching your application server’s response to avoid a duplicated workload.
This book will take you from the installation of the Varnish Cache server to defining caching policies, the normalization of static content, and a final production-ready fast and scalable cache server.
You will learn to balance requests across servers based on input data or pre-defined settings, create persisted sessions (sticky sessions), compress static content, and modify requests. If you want to improve the speed and also provide a fail-over mechanism to achieve a fast and available website, then this book is for you.
By the end of this book, you’ll learn how to scale and improve the user‘s experience by providing a fast and available website.
