Nginx Rewrite Rules

Nginx rewrite rules are directives used in the Nginx web server configuration to modify or redirect URLs, enabling URL rewriting, redirection, and request handling. They allow developers to create clean, SEO-friendly URLs, implement redirects (e.g., HTTP to HTTPS), and manage complex routing logic without changing application code. These rules are defined using the `rewrite` directive and regular expressions to match and transform incoming request URIs.

Also known as: Nginx URL Rewriting, Nginx Redirect Rules, Nginx Rewrite Module, ngx_http_rewrite_module, Nginx Rewrite Directives

Why learn Nginx Rewrite Rules?

Developers should learn Nginx rewrite rules when managing web servers to improve URL structure, handle legacy URL migrations, enforce security policies, or optimize SEO. Specific use cases include redirecting old URLs to new ones after a website redesign, implementing canonical URLs to avoid duplicate content, and setting up maintenance pages during deployments. They are essential for DevOps and backend engineers working with Nginx in production environments to ensure smooth user experiences and server performance.
