With an .htaccess file, you shall specify how the server that manages the requests to your web sites should act a number of scenarios. This is a text file with directives that are executed when somebody tries to open your website and what happens next is determined by the content of the file. As an illustration, you can block a specific IP address from accessing your website, which means that the server will decline the visitor’s request, or you can forward your domain to another URL, so the server may direct the visitor to the new web address. You could also use customized error pages or protect any part of your site with a password, if you place an .htaccess file inside the correct folder. Many well-known script-driven applications, including Joomla™, Drupal™ and WordPress, use an .htaccess file to operate properly.
