Symfony 3 environment driven by url - 404 on _wdt and _profile - .htaccess

Question

I would like to drive my environment (dev, prod) by URL
myuser.ENV.domain (eg : foo.dev.test.com or foo.prod.test.com)
So I decide to do some changes in .htaccess file
DirectoryIndex app.php
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{SERVER_NAME} mydevserver.priv?$
RewriteCond %{HTTP_HOST} ^(.+)\.(.+)\.(mydevserver.priv)?(:80)?$
RewriteRule .* - [E=SF_USER:%1,E=SF_ENV:%2,E=SF_SERVER:%3,QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ %{ENV:BASE}/app.php [L]
</IfModule>
Next, I do some changes in app.php
<?php
ini_set('memory_limit', '256M');
umask(0000);
use Symfony\Component\Debug\Debug;
use Symfony\Component\HttpFoundation\Request;
$env = filter_input(INPUT_SERVER, 'SF_ENV') ?: $_SERVER['SF_ENV'];
/** #var \Composer\Autoload\ClassLoader $loader */
$loader = require __DIR__ . '/../app/autoload.php';
if ('dev' === $env) {
$debug = true;
Debug::enable();
} elseif ('prod' === $env) {
include_once __DIR__ . '/../var/bootstrap.php.cache';
$debug = false;
} else {
throw new \Exception('Environment Not handled');
}
$kernel = new AppKernel($env, $debug);
$kernel->loadClassCache();
//$kernel = new AppCache($kernel);
// When using the HttpCache, you need to call the method in your front controller instead of relying on the configuration parameter
//Request::enableHttpMethodParameterOverride();
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);
When I go on the prod URL, I have the default success page of Symfony 3, without debug toolbar.
When I go on the dev URL, I have the default success page but I don't have the debug toolbar. There is a 404 error about _wdt & _profiler routes.
But, If I go on the file app_dev.php, I have the debug tool bar.
I probably miss a little thing but I can't figure out.
I did a fast test renaming app.php into index.php and remove the DirectoryIndex but it changes nothing.
If I user var_dump on my $env var, it gets the good env from environment variable SF_ENV.
Can someone help me ?

Not sure what's wrong exactly but setting up a virtual host might be simpler solution providing same results.
You have all the settings needed in Symfony virtual host documentation. If you choose to go that way and you are using Apache 2.4+ follow the mod_php settings. Also this version of Apache server has replaced
Order Allow,Deny
Allow from All
with:
Require all granted
You also have youtube video tutorials on how to setup virtual hosts. Here's an example of one of my virtual hosts which I made following the above mentioned documentation, vhost for a simple symfony app for testing:
<VirtualHost *:80>
ServerName www.login.com
DocumentRoot "C:/xampp/htdocs/symfUser/web"
<Directory "C:/xampp/htdocs/symfUser/web">
Require all granted
<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ app.php [QSA,L]
</IfModule>
</Directory>
<Directory "C:/xampp/htdocs/symfUser/web/bundles">
<IfModule mod_rewrite.c>
RewriteEngine Off
</IfModule>
</Directory>
