With an .htaccess file, you shall determine how the web server which deals with the requests to your web sites should act in different situations. This is a text file with directives that are carried out 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 certain IP address from opening the website, therefore the server will decline your visitor’s request, or you can redirect your domain name to some other URL, so the server may redirect the visitor to the new web address. You could also use personalized error pages or secure any part of your Internet site with a password, if you place an .htaccess file in the correct folder. Many popular script-driven applications, including Joomla™, WordPress and Drupal™, use an .htaccess file to work correctly.
