This book is a step-by-step, example-oriented tutorial that will teach you to implement Nginx modules, as well as how to extend Nginx with core and third party modules.Nginx Module Extension is intended for advanced users, system administrators, and developers of Nginx modules. You need to have prior experience with using Nginx as a web server and basic Nginx configuration changes. You also need basic understanding of GNU tools like configure and make, in order to be able to compile the source code.
