This can be done in php using following code:

if (!isset($_SERVER[‘PHP_AUTH_USER’])) { header(‘WWW-Authenticate: Basic realm=”My Realm”‘); header(‘HTTP/1.0 401 Unauthorized’); echo‘Text to send if user hits Cancel button’; exit; } else { echo

Hello {$_SERVER[‘PHP_AUTH_USER’]}.

; echo

You entered {$_SERVER[‘PHP_AUTH_PW’]} as your password.

; } ?>
