With an .htaccess file, you shall specify how the web server which deals with the requests to your Internet sites have to act in different occasions. This is a text file with directives that are performed when someone tries to open your Internet site and what happens next will depend on the content of the file. As an example, you may block a specific IP address from opening the Internet site, therefore the server will decline the visitor’s request, or you can redirect your domain to another URL, so the server will redirect the visitor to the new web address. You may also use personalized error pages or secure any part of your site with a password, if you place an .htaccess file inside the correct folder. Many popular script-driven apps, such as Joomla™, WordPress and Drupal™, use an .htaccess file to operate properly.
