With an .htaccess file, you can specify how the server that addresses the requests to your Internet sites should act in a variety of occasions. This is a text file with directives that are carried out when someone tries to open your website and what happens next is determined by the content of the file. For example, you can block a specific IP address from accessing the website, therefore the server will decline your visitor’s request, or you can forward your domain to an alternative URL, so the server will redirect the visitor to the new web address. You could also use custom-made error pages or preserve any part of your Internet site with a password, if you place an .htaccess file inside the correct folder. Many well-known script-driven apps, including WordPress, Joomla™ and Drupal™, use an .htaccess file to operate properly.
