With an .htaccess file, you'll determine how the server that addresses the requests to your Internet sites have to act a number of occasions. This is a text file with directives that are executed when an individual tries to open your website and what happens next will depend on the content of the file. As an example, you could block a specific IP address from opening the website, and the server will decline your visitor’s request, or you can redirect your domain to some other URL, so the server may redirect the visitor to the new web address. Also you can use customized error pages or preserve any part of your website with a password, if you place an .htaccess file inside the correct folder. Many widely used script-driven applications, such as Joomla™, Drupal™ and WordPress, use an .htaccess file to work correctly.
