function callXMLHttp()
{
try {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch(e) {
xmlHttp = new XMLHttpRequest();
} xmlHttp.onreadystatechange = function() {
if (xmlHttp.readyState == 4) {
if (xmlHttp.status == 200) {
var data = xmlHttp.responseText;
}
}
} xmlHttp.open("POST","XMLHttpServer.aspx);
xmlHttp.send(null);
} window.setInterval("callXMLHttp()",5000);
