[xwiki-devs] xredirect parameter after an upload action

Hello developers, I seem to see a regression whereby a POST to an /xwiki/bin/upload/ request no more uses the xredirect parameter and simply redirects to the page. Is this a known change? Is it supposed to have been working being undocumented and can try to find a fix? Or should I simply try to adjust the client (tremble tremble). thanks in advance Paul
