The browser will not be expecting a page back, and will ignore headers. 
Just some quick suggestion code, this isn't tested (except createRequest - 
I use that all the time)...

function createRequest() {
	try {
		request = new XMLHttpRequest();
		} catch (trymicrosoft) {
		try {
		request = new ActiveXObject("Msxml2.XMLHTTP");
		} catch (othermicrosoft) {
		try {
		request = new ActiveXObject("Microsoft.XMLHTTP");
		} catch (failed) {
		request = null;
		}
		}
	}
	if (request == null) alert("Error creating request object!");
   }

function sndReq(action) {
	createRequest();
	var url = "a.php?action=" + Volume + "&dummy=" + new Date().getTime(); 
	// random shit at the end is hack to get round browser response cacheing
	request.open("GET",url);
	request.onreadystatechange = updateReq;
	request.send(null);
	}

function updateReq() {
	if (request.readyState == 4) {
		var newLocation = request.responseText;
		window.location = newLocation;
		}
	}
