Create http://test.dwagn.org/wagn/left_card+right_card then look at http://test.dwagn.org/wagn/left_card

Created http://test.dwagn.org/wagn/lefty and http://test.dwagn.org/wagn/middley+*rform and then went to http://test.dwagn.org/wagn/lefty+middley (virtual) and created http://test.dwagn.org/wagn/lefty+middley+righty

http://test.dwagn.org/wagn/lefty+middley was created. I deleted it (and +righty), then again went to http://test.dwagn.org/wagn/lefty+middley (virtual) and created http://test.dwagn.org/wagn/lefty+middley+righty
