Apache HTTPD mod_rewrite is a powerful module that provides URL rewriting capabilities for the Apache HTTP Server (HTTPD). It allows administrators to manipulate URLs on-the-fly, rewriting incoming requests based on predefined rules and conditions. Mod_rewrite enables various URL transformations, including redirection, rewriting, and proxying, making it a versatile tool for enhancing website functionality and search engine optimization (SEO). With mod_rewrite, administrators can create complex rewriting rules using regular expressions to modify URLs, hide internal server structures, implement SEO-friendly URLs, and enforce canonical URLs. Additionally, mod_rewrite supports conditional rewriting based on request headers, query parameters, and environmental variables, enabling advanced URL manipulation logic. It is widely used in conjunction with other Apache modules to create sophisticated URL routing and rewriting configurations for web applications and websites. s://httpd.apache.org/docs/2.4/mod/mod_rewrite.html
