With an .htaccess file, you shall specify how the web server that manages the requests to your websites should act in different cases. This is a text file with directives that are performed when an individual tries to open your website and what happens next is determined by the content of the file. For example, you can block a specific IP address from accessing the Internet site, therefore the server will decline your visitor’s request, or you can redirect your domain name to a different URL, so the server may redirect the visitor to the new web address. Also you can use tailor-made error pages or secure any part of your site with a password, if you place an .htaccess file in the correct folder. Many widespread script-driven apps, such as WordPress, Drupal™ and Joomla™, use an .htaccess file to work properly.
