With an .htaccess file, you shall specify how the server that deals with the requests to your web sites have to act in various occasions. This is a text file with directives that are executed when somebody tries to open your Internet site and what happens next is determined by the content of the file. As an illustration, you may block a particular IP address from opening the Internet site, therefore the server will decline your visitor’s request, or you can redirect your domain to an alternative URL, so the server may direct the visitor to the new web address. You can also use personalized error pages or shield any part of your Internet site with a password, if you place an .htaccess file in the correct folder. Many widespread script-driven applications, like Joomla™, WordPress and Drupal™, use an .htaccess file to work properly.
