This document contains configuration examples for the Nginx web server. It shows how to use different location blocks to route requests based on the URL and return specific content. Location blocks can match the request URL exactly, use regular expressions to match parts of the URL, and specify a root directory to serve files under a specific path. The examples demonstrate how to configure Nginx to return different content based on the request URL and handle image file requests.
