		var progids = ['Microsoft.XMLHTTP', 'MSXML2.XMLHTTP'];
		for (var ndx = 3; ndx <= 6; ++ndx) {
			/* populate array */
			progids[progids.length] = 'MSXML2.XMLHTTP.' + ndx + '.0';
		}

		for (var i = 0; i < progids.length; i++) {
			progid = progids[i];
			try {
				return new ActiveXObject(progids[i]);
			} catch (ex) {
				progid = '';
			}
		}
		// if falls here no xmlhttpsupport
		return null;
	};
