XML HTTP and HTTP...

Dear All,

Can anybody tell me the difference between XHTTP and the usual http?

What is the difference between the following two codes?? Which is better and preferred??

In both the cases I am sending a request from the client to the server and the server returns an XML doc. The XML Doc is a dynamic Doc created by a ASPX page.

Code 1. Here a HTTP Request is sent from the Client to the Server and loads a XML Dom. This is then used to populate data into a ComboBox..

oXml = new ActiveXObject("Microsoft.XMLDOM");

oXml.async = true;

try

{

window.document.focus();

oXml.load("ABC.aspx?Querystring=S”);

oXml.onreadystatechange = funPopulateSel;

            }

            catch(e)

            {

                        alert(e);

            }

Code 2. Here is another code where in an xhttp request is sent from client to server. The response is loaded in to a XML Dom and is used to populate data into a combo box.

url="ABC.aspx?Querystring=S”

xmlhttp.open("GET",url,true);

xmlhttp.onreadystatechange=function() {

if (xmlhttp.readyState==4)

{

oXml = new ActiveXObject("Microsoft.XMLDOM");

oXml.load(xmlhttp.responseText);

oXml.onreadystatechange = funPopulateSel;

}

Which is better??

I prefer the first one because only one object is created J…

The second case is how a typical AJAX works…may be the response is not an XML.

Thanks And With Regards,
