Getting Started with Varnish Cache

I'm the author of "Getting Started with Varnish Cache", an O'Reilly book about the Varnish caching technology.

Varnish is a so-called reverse caching proxy that acts as an intermediary between the browser and the webserver. Varnish stores HTTP responses and serves them to the browser, without accessing the backend for every request. This causes a massive speed increase.

My book explains how you can get the most out of the software, by tuning either your Varnish configuration, or by optimizing your web application.
