How to Ensure URL Rewriting Functionality with mod_rewrite?

Understanding mod_rewrite

mod_rewrite is an Apache module that enables URL rewriting, allowing you to customize request URLs to improve site functionality or SEO. It's crucial to understand that mod_rewrite is independent of PHP.

Enabling mod_rewrite

1. Open the Apache configuration file httpd.conf located in:

   • Apache version 2.4: C:Program Files (x86)Apache Software FoundationApache2.4confhttpd.conf
   • Apache version 2.2: C:Program FilesApache Software FoundationApache2.2confhttpd.conf

2. Add the following line:

   LoadModule rewrite_module modules/mod_rewrite.so

macOS/Linux

1. Open the Apache configuration file httpd.conf or apache2.conf:

   • Ubuntu: /etc/apache2/apache2.conf
   • CentOS: /etc/httpd/conf/httpd.conf
   • macOS: /etc/apache2/httpd.conf

2. Add the following line:

   LoadModule rewrite_module modules/mod_rewrite.so

Testing if mod_rewrite is enabled

1. Create a .htaccess file in any web directory.

2. Add the line:

   RewriteEngine on
