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.

Session persistence

If you have a scenario where you have a load balancer with multiple backend servers (as we covered back in Chapter 8, Load Balancing), there can be some tricky scenarios where session tracking would be difficult to implement. While using the hash-based algorithm can ensure requests from the same IP is routed to the same backend, this doesn't always ensure a balanced distribution of requests.

One of the key features for NGINX Plus is session persistence, where requests from the same client need to be sent to the same server for the life of that session. Also known as "sticky" sessions, this can be especially important when it comes to payment systems, where the sharing of information between backend servers can be quite restrictive.
