First you will set up Nginx and understand the architectural nuances. Then you will learn how to scale out, secure, monitor and troubleshoot the web server.

Finally, you will learn to troubleshoot and maintain your Nginx professionally.
Written by an author who has gone through the rough phase while moving from IIS/Apache to Nginx, this book is practical and filled with step-by-step instructions to make your time with Nginx as straightforward as possible.

Esta estructura url era muy difícil de encontrar y no estaba documentada en ningún sitio al que pudiera llegar desde las búsquedas de Google. Desearía que Apple proveyera más transparencia a este tipo de puntos finales para permitir a la gente rebanar y cortar estos datos que están disponibles públicamente de otra manera, sólo que no en un formato amigable para las máquinas.
