Code says bool WebCoreSynchronousLoaderClient::canAuthenticateAgainstProtectionSpace(ResourceHandle*, const ProtectionSpace&) { // FIXME: We should ask FrameLoaderClient. return true; } We should fix the FIXME. Corresponding code for CFNetwork based loader is being added in bug 65190.
When this is fixed, we can fix the test from https://bugs.webkit.org/show_bug.cgi?id=159071 with WebKit1.
