function post(method,params)
{
	var r_txt ='{"jsonrpc":"2.0","method":"'+method+'","params":{'+params+'},"id":1234}';
	var http = new XMLHttpRequest();
	http.open("POST", 'http://foo.com:8082', true);
	http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
	http.setRequestHeader("Content-length", r_txt.length);
	http.setRequestHeader("Connection", "close");
	http.onreadystatechange = function() {
		if (http.readyState == 4) {
			if (http.status == 200) {    
			var obj = JSON.parse(http.responseText);
        		// read the response here
			print(JSON.stringify(obj));	                
			}
			else {
				print("http error:"+http.status);
			}
		}
	}
	http.send(r_txt);

//Then format the method and parameters and post it like this:
var query='"name":"Foobar","Hobbies":"Long walks on the beach.","Age":69';
post("foobarMethod",query);
