Varnish is an HTTP accelerator designed for content-heavy dynamic web sites. It stores data in virtual memory and leaves the task of deciding what is stored in memory and what gets paged out to disk to the operating system. This helps avoid the situation where the operating system starts caching data while they are moved to disk by the application.
Instant Varnish Cache How-to, will take readers 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. Readers will also, 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. Overall, this book is ideal for readers looking to improve the speed of their website, and provide a fail-over mechanism to achieve a fast and available website.
The book gives clear instructions on how to:
- Install and configure Varnish Cache
- Connect application servers to Varnish Cache
- Load balance requests
- Request and response workflow inside the Varnish
- Caching and compressing static content
- Session and cookie handling

This book is aimed at system administrators and web developers who need to scale websites without tossing money on a large and costly infrastructure.
