With an .htaccess file, you can determine how the server which addresses the requests to your websites must act in different scenarios. This is a text file with directives that are executed when an individual tries to open your website and what happens next is determined by the content of the file. As an illustration, you could block a particular IP address from opening the Internet site, so the server will decline your visitor’s request, or you can redirect your domain to an alternative URL, so the server will direct the visitor to the new web address. You may also use customized error pages or preserve any part of your website with a password, if you place an .htaccess file inside the correct folder. Many widespread script-driven applications, such as WordPress, Drupal™ and Joomla™, use an .htaccess file to function properly.
