1. Describe the steps for the application initialization.
2. Change a website from within index.php.

I. Describe the steps for application initialization

• Run the file index.php
• Include Mage.php

● If not existing => redirect to the downloader of  magento

● If existing a file Mage.php => Conduct the command: Mage::run($mageRunCode, $mageRunType);

• App::run($mageRunCode, $mageRunType)

● Load configuration files in app/etc/modules

● Load configuration files in the module (app/code/core/Mage/Customer/etc/config.xml)

● Update/create version of modules in core_resource

● Use routers to define the controller and action requested

● Call dispatch() of the controller that is requested

● Call action of the controller that is requested

II. Change a website from within index.php

Change the website and uses of index.php by the following steps:

Step 1: Create Website

• Generate catalog, root category (Catalog > Manage Categories)
• Manage store, create website, store and store view (System > Manage Stores)
• Configure Base Url for the website which has been created (System > Configuration tab Web)

Step 2: Insert the code below into index.php before the command: Mage::run($mageRunCode, $mageRunType);

switch($_SERVER['HTTP_HOST']) {
	case 'name_domain_1':
	case 'name_domain_n':
		$mageRunCode = 'website_code';
		$mageRunType = 'website';
	break;
}
