I use this all the time for intranet development. It is really useful for client-side
validation and dynamic page building. For validation, use the object to post values
to a page and then wait for the results. In one application, I use this to validate
state/country/postal code combinations. This is great because it doesn't require
posting the actual data entry form until it is totally validated.
For dynamic page building, I use the object in conjuction with a DHTML tab control
that I created. Waiting for the entire page to load with all of the tabs populated
can take a long time. I get around this by loading the page with only the first tab
populated and then the onLoad event of the body tag fires off successive calls to
XMLHTTP to get the content for the other tabs. This content is assigned to the
innerHTML of each tab.
Here is a JS function which wraps the calls. The paramater sContent contains pair
values that will be posted to sPage (seperate multiple values with an ampersand).
function postPage( sContent, sPage )
{
var oHTTP;
var sRetVal;
oHTTP = new ActiveXObject('Microsoft.XMLHTTP');
oHTTP.Open('POST', sPage, false);
oHTTP.setRequestHeader('Content-type','application/x-www-form-urlencoded');
oHTTP.Send(sContent);
sRetVal = oHTTP.responseText;
oHTTP = '';
// This will remove all tags from the output, which may be added by
// application.cfm.
return sRetVal.replace(/<[^<>]*>/g,'');
}

Hope this helps.
