With an .htaccess file, you shall specify how the server which addresses the requests to your Internet sites have to act in various situations. This is a text file with directives that are carried out when somebody tries to open your Internet site and what happens next will depend on the content of the file. For instance, you could block a specific IP address from accessing your website, which means that the server will decline your visitor’s request, or you can forward your domain name to some other URL, so the server will direct the visitor to the new web address. You could also use custom-made error pages or shield any part of your Internet site with a password, if you place an .htaccess file in the correct folder. Many popular script-driven applications, like Joomla™, WordPress and Drupal™, use an .htaccess file to operate properly.
