);

Avoid declaring same URI on multiple domains with this solution.

See below for multi-domains with same URI.

For multiple domains with same URI

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;

class DomainMiddleware
{
    public function handle(Request $request, Closure $next, string $urlEncodedCsvUrls): mixed
    {
        if (\str_contains(\urldecode($urlEncodedCsvUrls), $_SERVER['HTTP_HOST'] ?? '*')) {
            return $next($request);
        }

        return \response(status: 404);
    }
}



// bootstrap/app.php

$app->routeMiddleware([
     'url.encoded.domains' => \App\Http\Middleware\DomainMiddleware::class,
]);

// routes/web.php
$domains = \urlencode(\rtrim(\env('APP_URL2'), ',') . ',' . \env('APP_URL'));


$router->group(
    [
        'middleware' => ['url.encoded.domains:' . $domains],
    ],
    function (Router $router): void {
        $router->post('/login', 'Auth\AuthController@login');
    }
);
