Hi,
Small tips on the Ajax Object,

Microsoft™ and Internet Explorer use an object called XMLHttp instead of the XMLHttpRequest object used by Mozilla, Opera, Safari, and most non-Microsoft browsers. For the sake of simplicity, I refer to both of these object types simply as XMLHttpRequest. This matches the common practice you'll find all over the Web and is also in line with Microsoft's intentions of using XMLHttpRequest as the name of their request object in Internet Explorer 7.0.

Ajax Object Initialization in javascript

if (window.XMLHttpRequest)
{ // Mozilla, Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
http_request.overrideMimeType('text/xml');
}
}
else if (window.ActiveXObject)
{ // IE
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
try {
http_request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
}

we can initialize Object for Ajax component in the above way
