For the development purposes I want to have 2 app folders for the one shop.
I want to choose which folder to use as “app” by IP.
Then I suggested that I can do it in the index.php file. I found where the app/Mage.php includes and changed it to:
$mageFilename = 'app_1401/Mage.php';
$mageFilename = 'app/Mage.php';
But the store doesn’t want to work.
How to make Magento use app_1401 and nothing more?
