I was wrong about the reason. DumpRenderTree allows the load, but it doesn't show up because the test finishes before the subframe loads.

Looks like there may be two bugs:

1. WebCore dispatches a load event too early when going back. This happens in FrameLoader::retryAfterFailedCacheOnlyMainResourceLoad() when it calls stopAllLoaders(), but the load is not done yet, it is continued to attempt resubmitting the form!

2. Not quite sure what happens on platforms that fail the current test results. Perhaps they ignore Cache-Control, and cache the result of form submission anyway? Could someone please set a breakpoint in FrameLoader::retryAfterFailedCacheOnlyMainResourceLoad() and see if it's hit?

So, Qt/Gtk/EFL results are what the test should print if not for issue (1), but they are probably like that because of another bug only, not because the right thing happens.
