Overview of this book

NGINX Cookbook covers the basics of configuring NGINX as a web server for use with common web frameworks such as WordPress and Ruby on Rails, through to utilization as a reverse proxy. Designed as a go-to reference guide, this book will give you practical answers based on real-world deployments to get you up and running quickly. Recipes have also been provided for multiple SSL configurations, different logging scenarios, practical rewrites, and multiple load balancing scenarios. Advanced topics include covering bandwidth management, Docker container usage, performance tuning, OpenResty, and the NGINX Plus commercial features. By the time you've read this book, you will be able to adapt and use a wide variety of NGINX implementations to solve any problems you have.

Enhancing NGINX with keep alive

Using a persistent HTTP connection between the server and the browser speeds up additional requests, as there's no extra handshaking required. Especially over more latent connections, this can increase the overall performance. If NGINX is being used as a reverse proxy (as detailed in Chapter 7, Reverse Proxy), it's also important to ensure that these connections have keepalive enabled to ensure high throughput while minimizing latency. The following diagram highlights both areas where the keepalive packets are important to maintain high performance:

This persistent connection remains established using Keep Alive packets, so that the connections remain open for minutes rather than closing once they are complete. This reuse can be immediate for additional CSS/JS files or as further pages and resources are requested.
