With an .htaccess file, you will determine how the web server which addresses the requests to your Internet sites must act a number of occasions. This is a text file with directives that are carried out when somebody tries to open your website and what happens next is determined by the content of the file. For example, you could block a specific IP address from accessing your website, so the server will decline the visitor’s request, or you can redirect your domain name to a different URL, so the server will redirect the visitor to the new web address. You can also use personalized error pages or protect any part of your site with a password, if you place an .htaccess file in the correct folder. Many popular script-driven apps, including Drupal™, Joomla™ and WordPress, use an .htaccess file to operate efficiently.
