With an .htaccess file, you will determine how the web server that handles the requests to your Internet sites must act a number of cases. This is a text file with directives that are carried out when an individual tries to open your site and what happens next is determined by the content of the file. For example, you can block a particular IP address from opening the website, and the server will decline your visitor’s request, or you can forward your domain name to some other URL, so the server will redirect the visitor to the new web address. You can also use personalized error pages or secure any part of your site with a password, if you place an .htaccess file in the correct folder. Many widely used script-driven applications, such as Joomla™, WordPress and Drupal™, use an .htaccess file to operate efficiently.
