With an .htaccess file, you shall specify how the server which handles the requests to your Internet sites must act in various scenarios. This is a text file with directives that are performed when someone tries to open your website and what happens next is determined by the content of the file. For example, you could block a particular IP address from opening your website, so the server will decline your visitor’s request, or you can redirect your domain to another URL, so the server may redirect the visitor to the new web address. Also you can use custom-made error pages or shield 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 efficiently.
