Question

var url:String = "http://www.[yourDomain].com/application.jsp";
var request:URLRequest = new URLRequest(url);

var variables:URLVariables = new URLVariables();
variables.exampleSessionId = new Date().getTime();
variables.exampleUserLabel = "guest";
request.data = variables;
request.method = URLRequestMethod.POST;

navigateToURL(request);

This example is the functionality I want to achieve, however i want to make this happen in the background. This code opens a window.

You need to create a URLLoader and call its load() method to do stuff “in the background”.

var url:String = "http://www.[yourDomain].com/application.jsp";
var request:URLRequest = new URLRequest(url);

var variables:URLVariables = new URLVariables();
variables.exampleSessionId = new Date().getTime();
variables.exampleUserLabel = "guest";

request.data = variables;
request.method = URLRequestMethod.POST;

var ldr:URLLoader = new URLLoader();
ldr.load(req);

If you’re sending data back then you can manage this through an Event.

ldr.addEventListener(Event.COMPLETE, _dataBack);

function _dataBack(e:Event):void
{
    var vars:URLVariables = new URLVariables(e.target.data);
    //do stuff with vars

    removeEventListener(Event.COMPLETE, _dataBack);
}
