You can not use the XMLHTTPRequest object on different domains.

If the other domain is returning back JSON you can you the script tag method.

Example here using Yahoo's JSON Webservice:

Well... you can use the XMLHTTPRequest to send a request to a server-side application (on the same domain) which is able to perform a cross-domain request.

For instance here is a (tested) AJAX & PHP cross-domain request solution: http://www.troywolf.com/articles/

Should be similar solution with ASP, Java, Pearl...

OP: If you tell us what server-side languages you have available (php/asp/jsp) I can write you a steal-page script that will accept a url as the only parameter and output that page's contents. It will allow you to ajax any page on the internet no problem.

i am using visual basic asp .net as server side programming.
itsallkizza! i am still stuck with this problem.

any help would be appreciated
thanks

I wrote a "steal_page.asp" for you. You can use JS to ajax this page, passing along the url of the page you want to grab. You can now ajax any page on the internet using JS and steal_page.asp:

<%@ language="javascript"%>
<%

var url_to_steal = String(Request.QueryString("page_url"));
if (url_to_steal.charAt(0) == '"') url_to_steal = url_to_steal.substring(1,url_to_steal.length-1);

if (!url_to_steal) Response.Write("null");
else
{
var xmlhttp = Server.CreateObject("MSXML2.ServerXMLHTTP.3.0");
xmlhttp.open("GET",url_to_steal,false);
xmlhttp.send("");
Response.Write(xmlhttp.responseText);
xmlhttp = null;
}

%>


For an example, you can grab google.com from your JS by ajaxing this url: /steal_page.asp?page_url=http://www.google.com
(or) /steal_page.asp?page_url="http://www.google.com"
