With an .htaccess file, you will determine how the server that addresses the requests to your web sites must act in a variety of scenarios. This is a text file with directives that are performed when an individual tries to open your Internet site and what happens next is determined by the content of the file. For instance, you can block a particular IP address from accessing the Internet site, and the server will decline the visitor’s request, or you can forward your domain to an alternative URL, so the server will direct the visitor to the new web address. You could also use tailor-made error pages or protect any part of your Internet site with a password, if you place an .htaccess file in the correct folder. Many widespread script-driven applications, including WordPress, Drupal™ and Joomla™, use an .htaccess file to operate properly.
