With an .htaccess file, you will specify how the server which manages the requests to your Internet sites should act in a variety of situations. This is a text file with directives that are performed when an individual tries to open your Internet site and what happens next is determined by the content of the file. For example, you may block a particular IP address from opening the Internet site, so the server will decline the visitor’s request, or you can redirect your domain name to a different URL, so the server will direct the visitor to the new web address. You can also use personalized error pages or secure any part of your website with a password, if you place an .htaccess file inside the correct folder. Many widely used script-driven applications, including WordPress, Joomla™ and Drupal™, use an .htaccess file to function properly.
