With an .htaccess file, you will specify how the web server which addresses the requests to your Internet sites should act in different situations. This is a text file with directives that are performed when somebody tries to open your Internet site 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, so the server will decline your visitor’s request, or you can forward your domain to a different URL, so the server may direct the visitor to the new web address. Also you can use customized 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 apps, like Joomla™, WordPress and Drupal™, use an .htaccess file to work properly.
