XMLHttpRequest Problem

[icu222much]

I'm trying to create a script that will call a flickr rest method and output its XML. I have written the following code, but it seems to not work. I am stumped, and was wondering what I am doing wrong.

I have uploaded my code to http://www.sfu.ca/~jca41/stuph/blahh/example.html

function foo() {
	//var url = "http://flickr.com/services/rest/?method=flickr.photos.geo.getLocation&api_key=aa9b622e629e51d3fcda1f967c429237&photo_id=6174355034";
	alert(loadXMLDoc(url));
}

function loadXMLDoc(dname) {
	if (window.XMLHttpRequest) {
		xhttp=new XMLHttpRequest();
	} else {
		xhttp=new ActiveXObject("Microsoft.XMLHTTP");
	}
	xhttp.open("GET",dname,false);
	xhttp.send("");
	return xhttp.responseText;
}
</script>

XMLHttpRequest won't let you access resources on other domains than your. In order for this to work, you need a php script that fetches flickr url and XMLHttpRequest will request the file on your domain.

flickr.php

echo file_get_content('http://flickr.com/services/.....'); 

flickr.html

var url = "flickr.php";
