The relevent code (it's a basic example):

var XMLHTTP = GetXMLHTTP();
if(XMLHTTP != null)
{
 XMLHTTP.open("GET","default.aspx");
 XMLHTTP.onreadystatechanged = stateChanged;
 XMLHTTP.send(null);
} //end if(XMLHTTP != null)

function stateChanged()
{
 if(XMLHTTP.readyState == 4 && XMLHTTP.status == 200)
 {
   window.alert(XMLHTTP.responseText);
 } //end if
}//end function stateChanged

When I run this in the browser, I get a javascript exception for the
"XMLHTTP.send(null);" line:
"Object does not support this property or method."

Help...?

Thanks,
