Media Server :: Using LoadVars In SSAS To Send Data To A Php File?

I am using FMS 4.5 and have a simple application which I want to use to send two strings to a php file. But I get a compilation error whenever I try to assign any value to these objects:
 
Here is main.asc:
 
<code>
var variables = new LoadVars();
variables.username = "uname";
variables.send(http://url.abc.com/test.php,POST)
</code>
  
I can't compile with the second line. FMS just says: Sending error message: Compilation error
 
How do I send variables to a HTTP URL?
