[PATCH] JavaScript XMLHttpRequest.open should throw exception

[Kazuki Ohta]

Hi, All.

I continue to write Ajax program on Konqueror and found 
another imcompatible behavior. Regarding the security 
issue, XMLHttpRequest.open cannot connect to the 
different domain from the document domain.
When one tries to connect to the different domain, IE / 
Gecko / Opera throws exception but KHTML does not.
Please have a look at the example code below.

var req = createXMLHttpRequest();
try {
   req.open("GET", 'http://example.com/', true);
   req.send(null);
}
catch(e) {
 /* IE/Gecko/Opera reaches here */
  if(typeof e == 'object') {
    alert(e.message);
  } else {
    alert(e);
  }
}

Attached patch changes to throw exception like 
IE/Gecho/Opera. Please review the patch and can I apply 
this patch?

thanks in advance:-)
