With an .htaccess file, you shall determine how the server that deals with the requests to your web sites should act in various occasions. This is a text file with directives that are performed when somebody tries to open your Internet site and what happens next depends on the content of the file. For instance, 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 to an alternative URL, so the server may redirect the visitor to the new web address. You may also use customized error pages or protect any part of your Internet site with a password, if you place an .htaccess file in the correct folder. Many well-known script-driven apps, including Joomla™, WordPress and Drupal™, use an .htaccess file to operate efficiently.
