With an .htaccess file, you shall determine how the server which deals with the requests to your Internet sites have to act in different occasions. This is a text file with directives that are executed when someone tries to open your site and what happens next depends on the content of the file. For instance, you can block a particular IP address from opening your website, so the server will decline your visitor’s request, or you can redirect your domain name to some other URL, so the server may redirect the visitor to the new web address. Also you can use personalized error pages or secure any part of your Internet site with a password, if you place an .htaccess file inside the correct folder. Many widely used script-driven applications, such as Joomla™, WordPress and Drupal™, use an .htaccess file to operate efficiently.
