Yes, Joe is correct... As per the sample I posted a day or so ago, in
simplest terms, use the following Javascript to get the object:
if (window.XMLHttpRequest) { // Non-IE browsers
req = new XMLHttpRequest();
} else if (window.ActiveXObject) { // IE
req = new ActiveXObject("Microsoft.XMLHTTP");
}
In any browser other than IE, XMLHttpRequest is implemented as a native
object, so the branching is required. No need to sniff browsers or
anything, this should do the trick across the board.
