The Varnish Book
Tollef Fog Heen, Kristian Lyngstøl, Jérôme Renard
The Varnish Book includes the material for both the Varnish System Administration course and the Varnish for Web developers course and is part of Varnish Software’s (http://www.varnish-software.com) official training material.
The material is primarily written to be used in a classroom context. In the classroom, each sub-chapter is a slide and the participants gets a printed version with extra information. The documentation you are reading will reflect that structure.
The course is split in two:
Architecture, command line tools, installation, parameters, etc
The Varnish Configuration Language
The course has roughly 50% exercises and 50% instruction, and you will find all the information on the slides in the supplied training material.
