+	 * I tried to connect to signal "resource-response-received"
+	 * of WebKitWebView but the SoupMessage instance was not
+	 * exactly the same which were sent or received by SoupSession.
+	 * So I could not cancel the SoupMessage or better: I cancelled
+	 * a SoupMessage which is not be handled so it had no effect.
+	 * The body of SoupMessage was still being loaded and javascript
+	 * was executed. I think the problem is that webkit-gtk creates
+	 * a copy of the real SoupMessage which is going to be sent and
+	 * received.
+	 * 
+	 * So I decided to connect to signal "got-headers" of every
+	 * SoupMessage sent by the default SoupSession which I notice
+	 * by connecting to signal "request-started" of SoupSession. Each
+	 * NoJSView connects to signal "resource-request-starting" of
+	 * WebKitWebView to remember each URI going to be loaded. When
+	 * a SoupMessage hits "got-headers" and is a javascript resource
+	 * I can cancel the message immediately and clear the body which
+	 * causes webkit-gtk to copy a empty body if it does at all as the
+	 * SoupMessage was cancelled. Then I emit this signal
+	 * "uri-load-policy-status" to notify each view but the cancellation.
+	 * (It also notifies all views if it is going to load to keep the
