With an .htaccess file, you can specify how the web server which handles the requests to your websites have to act in various situations. This is a text file with directives that are performed when somebody tries to open your website and what happens next is determined by the content of the file. For example, you may block a specific IP address from opening the website, and the server will decline your visitor’s request, or you can forward your domain name to another URL, so the server may direct the visitor to the new web address. Also you can use tailor-made error pages or shield any part of your Internet site with a password, if you place an .htaccess file in the correct folder. Many well-known script-driven applications, such as WordPress, Drupal™ and Joomla™, use an .htaccess file to work efficiently.
