Get o Post method without open browser

Hello everyone …
I would like to know how can I send a GET request (or the exe file or web player) to a php server that detects the content and open an HTML page … all without opening your browser … In fact, if I use the Application.OpenURL works, but I’m interested in making it clear to the player … how do I do? help me …

function sendForm() {
var mysite="http://xxx.xxx.xxx.xxx:2650/PHPPage.php";
var text= "ferrari";
var url = mysite + "?marca=" + text;
Application.OpenURL(url);}

You want to use the WWW class, documented here:
