function creatXMLHttp(){
try
{

xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
//alert ("You are using Microsoft Internet Explorer.");
}
catch (e)

//If not, then use the older active x object.
try
{
//If we are using Internet Explorer.

//alert ("You are using Microsoft Internet Explorer");
}
catch (E)
{
//Else we must be using a non-IE browser.
xmlhttp = false;
}
}
//If we are using a non-IE browser, create a javascript instance of the object.

{
xmlhttp = new XMLHttpRequest();
//alert ("You are not using Microsoft Internet Explorer");
}
}
function makerequest(serverPage, objID)

creatXMLHttp();
var obj = document.getElementById(objID);
xmlhttp.open("GET", serverPage);
xmlhttp.onreadystatechange = function()
{
if (xmlhttp.readyState == 4 && xmlhttp.status == 200)
{
obj.innerHTML = xmlhttp.responseText;
}
}
xmlhttp.send(null);
