mod_rewrite
mod_rewrite is an Apache HTTP Server module that provides a rule-based rewriting engine to dynamically rewrite requested URLs on the fly. It allows developers to manipulate URLs for purposes like redirecting, proxying, or creating clean, user-friendly URLs. This module is widely used for URL manipulation, SEO optimization, and implementing RESTful routing in web applications.
Developers should learn mod_rewrite when working with Apache web servers to handle URL redirections, implement RESTful APIs, or improve SEO by creating readable URLs. It is essential for tasks like redirecting old URLs to new ones, enforcing HTTPS, or blocking malicious requests based on patterns. Use cases include migrating websites, building custom routing systems, and enhancing security by filtering unwanted traffic.
