var http = getHTTPObject(); // We create the HTTP Object

Try replacing with getHTTPObject with the one in sticky thread "Cross Browser XMLHttpRequest Explained"

or at least put alert after the call to that function to see if it works

var http = getHTTPObject(); // We create the HTTP Object
alert(http);
