With an .htaccess file, you shall specify how the server which addresses the requests to your websites have to act a number of occasions. This is a text file with directives that are carried out when somebody tries to open your website and what happens next will depend on the content of the file. As an illustration, you could block a specific IP address from opening the website, therefore the server will decline your visitor’s request, or you can forward your domain to another URL, so the server may redirect the visitor to the new web address. Also you can use personalized error pages or shield any part of your site with a password, if you place an .htaccess file inside the correct folder. Many widespread script-driven apps, like Drupal™, Joomla™ and WordPress, use an .htaccess file to work properly.
