        <pre>I noticed that after enabling speculative revalidation in the GTk+ port the unit test /webkit2/WebKitWebResource/response started to fail in the bots:

  /webkit2/WebKitWebResource/response:                                 **

ERROR:../../Tools/TestWebKitAPI/Tests/WebKit2Gtk/TestResources.cpp:417:void testWebResourceResponse(SingleResourceLoadTest*, gconstpointer): assertion failed (webkit_uri_response_get_status_code(response) == SOUP_STATUS_NOT_MODIFIED): (200 == 304)

FAIL

We are simply doing a reload and checking that the response code we get for a subresource is 304, but now is 200, because the network process is using a preloaded entry. I would expect that in case of successful speculative revalidation, 304 was returned like a normal revalidation request, and the resource be loaded from the memory cache.</pre>
