With an .htaccess file, you will specify how the web server that addresses the requests to your Internet sites should act in different situations. This is a text file with directives that are executed when somebody tries to open your website and what happens next is determined by the content of the file. As an example, you may block a specific IP address from opening the site, which means that the server will decline your visitor’s request, or you can forward your domain name to another URL, so the server will direct the visitor to the new web address. You can also use personalized error pages or secure any part of your Internet site with a password, if you place an .htaccess file in the correct folder. Many popular script-driven applications, like WordPress, Drupal™ and Joomla™, use an .htaccess file to function efficiently.
