Apache Rewrite Rules

Apache Rewrite Rules are directives used in the Apache HTTP Server's configuration (typically in .htaccess files or httpd.conf) to manipulate URLs and control request routing. They are implemented through the mod_rewrite module, allowing developers to rewrite, redirect, or block URLs based on patterns and conditions. This enables tasks like creating clean URLs, implementing redirects for SEO, and securing web applications.

Also known as: mod_rewrite, Apache mod_rewrite, htaccess rewrite rules, URL rewriting, Apache redirect rules

Why learn Apache Rewrite Rules?

Developers should learn Apache Rewrite Rules when working with Apache web servers to manage URL structures, handle legacy URL migrations, or enforce security policies. They are essential for SEO optimization by redirecting old URLs to new ones, creating user-friendly URLs without query strings, and preventing hotlinking of resources. Use cases include setting up canonical URLs, implementing maintenance pages, and blocking malicious requests based on IP addresses or user agents.
