With the advent of high speed Internet access, short loading times and fast transfer rates have become a necessity.

In addition, the complete directive reference will be your best friend at all stages of the configuration and maintenance processes.</p> <p>This book is the perfect companion for both Nginx beginners and experienced administrators. For beginners, it will take you through the complete process of setting up this lightweight HTTP server on your system and configuring its various modules to get it to do exactly what you need, in a fast and secure way. For more experienced administrators, this book provides different angles of approach that can help you make the most of your current infrastructure. Nginx can be employed in many situations, whether you are looking to construct an entirely new web-serving architecture or simply want to integrate an efficient tool to optimize your site loading speeds.</p> <p>This book takes you through the setup and configuration of Nginx by detailing every step of the way, from downloading to configuring your server in a selection of common architectures.</p>

This solution is not only more interesting for your visitors, but also for search engines—URL rewriting is a key element to Search Engine Optimization (SEO).
