With an .htaccess file, you shall specify how the server that handles the requests to your Internet sites should act in a variety of occasions. 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 instance, you can block a specific IP address from accessing the site, and the server will decline the visitor’s request, or you can forward your domain to an alternative URL, so the server will direct the visitor to the new web address. Also you can use customized error pages or protect any part of your site with a password, if you place an .htaccess file inside the correct folder. Many widely used script-driven apps, like Joomla™, WordPress and Drupal™, use an .htaccess file to function correctly.
