The technique
The site is built with PHP, JavaScript and HTML. When the visitor presses the Enter button it runs a javascript that prints the value in the input field. When the visitor presses [Enter] an ajax-request sent to answer.php. The string runs through a lot of regex and after 50ms to 200ms you will get your answer on the screen, all online!
