Download the Varnish Book Update

It’s finally here. The latest edition of the Varnish Book for Varnish 4 and Varnish Plus. This edition is a major revision that updates the content from Varnish 3 to Varnish 4 and adds new content for Varnish Plus including Varnish Administration Console (VAC), Varnish Custom Statistics (VCS), Massive Storage Engine (MSE), SSL/TLS support and more. It also clearly illustrates differences between the open source Varnish Cache and the enhanced commercial edition Varnish Cache Plus.

The Varnish Book is a part of our efforts to maintain high-quality software documentation, contribute to the community and offer courses to master web caching with Varnish. This book is constantly updated and written in collaboration with our core developers and with feedback from our instructors and partners on what needs to be taught in order to deeply understand the Varnish technology.

With this book, we also aim to lower the entry barrier for newcomers by introducing basic concepts, such as the Varnish Configuration Language (VCL), and describing how to install and configure your Varnish server. More experienced Varnish developers can go directly to the chapter that covers in-depth their topic of interest.

Our training courses are the best way to become an expert in Varnish. Therefore, we have designed this book to be used as training material in our courses; however, you can also use it as self-instructional manual by working through, solving the exercises and comparing your results with our suggested solutions. Anyway, regardless of your preferred learning methodology and expertise level, we invite you to take a look at our training courses.

The book is available in HTML and PDF formats. In addition, you have access to the source code, so that you can build it in other formats, such as ePub. In the spirit of any other open source project, we also welcome your feedback as an important contribution.

That being said, we hope you learn from the book as much as we have enjoyed writing it!
