<?php
/**
 * DISABLED: 2025-09-14
 * This middleware was disabled as it appears to be a leftover from an earlier failed routing attempt.
 * RSX routing is now handled through the 404 exception handler in app/Exceptions/Handler.php.
 *
 * This file is kept for observation in case any key functionality needs to be restored:
 * - Automatic cache clearing in development mode
 * - Path exclusion for certain prefixes (_debugbar, horizon, telescope, etc.)
 * - Session initialization for RSX requests
 * - RSX debugging headers
 *
 * To re-enable this middleware:
 * 1. Rename file back to RsxMiddleware.php (remove .disabled extension)
 * 2. Re-add to app/Http/Kernel.php:
 *    protected $routeMiddleware = [
 *        'rsx' => \App\Http\Middleware\RsxMiddleware::class,
 *    ];
 *
 * CODING CONVENTION:
 * This file follows the coding convention where variable_names and function_names
 * use snake_case (underscore_wherever_possible).
