.htaccess Configuration (Deployed Only)

This project leverages a robust .htaccess file (not maintained locally or in this repository) to ensure secure and seamless functionality. Below is an outline of the key rules configured:

• Disable Directory Listing: Prevents directory contents from being exposed to unauthorized users
• Protect .htaccess File: Restricts access to the .htaccess file itself.
• Block Sensitive Files: Denies access to files containing sensitive information (e.g. .env, .json).
• Restrict PHP File Access: Limits access to specific PHP files to avoid unauthorized use.
• Secure Directories: Prevents access to sensitive directories (e.g. logs, media).
• Localhost-Only Scripts: Ensures certain scripts are accessible only from 127.0.0.1, enabling secure execution by Cron jobs in this project's context.
• Hide Server Details: Removes the X-Powered-By header for security.
• Enforce HTTPS: Redirects all HTTP requests to HTTPS for secure communication.
• URL Token Validation: Validates tokens in password recovery URLs to prevent misuse.
• Redirect All PHP Files: Redirects .php files to index.php unless explicitly whitelisted.
• Remove .php Extensions: Enables cleaner URLs by omitting the .php extension.
• Cache Static Assets: Sets long-term caching for static files (e.g., CSS, fonts) to enhance performance.

This .htaccess setup ensures secure, efficient, and professional deployment of the application.
