RenderProcessHost::FilterURL performs some security checks whether the URL coming from the renderer process is a valid one. In some cases it rewrites the URL to about:blank to avoid committing URL that is not valid for the renderer process. This CL adds a #blocked reference fragment to the URL, so it is easier to spot when this logic has taken effect and distinguish it from regular navigations to about:blank URLs.
