In my code I get the URL from the WebKitNetworkRequest and it always
worked fine. Please not that I didn't do too many requests with my
sample program.

Here's the code snippet that I used, it's in Perl using GIR but you
should be able to figure out what's going on:

        # Add a callback to monitor where each URI will go and reject
the URI if the
        # location differs from the original website.
        # This only blocks, iframes and clicked links. Javascript and
CSS are not blocked.
        $view->signal_connect("navigation-policy-decision-requested" => sub {
            my ($view, $frame, $request, $action, $decision) = @_;

            my $host_port = get_host_port($request->get_uri);

            # We allow browsing the same site
            return FALSE if $host_port eq $allowed_host_port;

            # We block the access to an external site
            print "Block access to $host_port\n";
            $decision->ignore();
            return TRUE;
        });
