With an .htaccess file, you will specify how the web server that handles the requests to your websites should act in different occasions. This is a text file with directives that are carried out when an individual tries to open your website and what happens next is determined by the content of the file. For instance, you could block a particular IP address from opening your website, and the server will decline your visitor’s request, or you can forward your domain to some other URL, so the server will redirect the visitor to the new web address. You may also use tailor-made error pages or shield any part of your website with a password, if you place an .htaccess file inside the correct folder. Many widespread script-driven applications, including WordPress, Joomla™ and Drupal™, use an .htaccess file to function correctly.
