------- Additional Comments from Alexey Proskuryakov <ap at webkit.org>
+	     if (window.layoutTestController)
+		 layoutTestController.notifyDone();
+	     log("PASS");

The PASS string is printed after notifyDone(), so I'm very surprised it shows
up in expected results.

+    if (m_sendResourceLoadCallbacks)
+	 return frameLoader()->client()->willCacheResponse(documentLoader(),
identifier(), response);
+    return 0;

Our usual style is to do early return (if (!m_sendResourceLoadCallbacks) return
0;). Some say that's bad for performance though, so we may need to reconsider
it eventually.

I don't think this has much to do with the resource being missing - more
likely, it's just that the response is cacheable, unlike what a CGI from
methods.html sends. It would be nice to make this clearer in ChangeLog and test
comments.
