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);}
