With an .htaccess file, you shall determine how the web server which deals with the requests to your Internet sites have to act a number of cases. This is a text file with directives that are performed when an individual tries to open your site and what happens next is determined by the content of the file. For example, you could block a particular IP address from opening the Internet site, and the server will decline the visitor’s request, or you can forward your domain to some other URL, so the server may redirect the visitor to the new web address. You may also use tailor-made error pages or preserve any part of your Internet site with a password, if you place an .htaccess file inside the correct folder. Many widespread script-driven applications, like Drupal™, Joomla™ and WordPress, use an .htaccess file to function correctly.
