The next step is to configure the web server to use the index.php file for indexes. To do this, log into WebTool, click the System menu, choose World Wide Web Management, then select Edit Virtual Hosts from the Module menu. Select your virtual host and you will be presented with a screen like the one in Figure 5-1.
As you can see we added index.php to the Directory Index field. After adding index.php click the Save This Virtual Host button to commit your changes.
