With an .htaccess file, you'll define how the web server that addresses the requests to your websites must act a number of situations. This is a text file with directives that are executed when an individual tries to open your website and what happens next will depend on the content of the file. For example, you may block a particular IP address from accessing your website, so the server will decline your visitor’s request, or you can forward your domain to another URL, so the server will direct the visitor to the new web address. You may also use custom-made error pages or shield any part of your Internet site with a password, if you place an .htaccess file inside the correct folder. Many widespread script-driven apps, like WordPress, Drupal™ and Joomla™, use an .htaccess file to operate properly.
