Comment 1 for bug 143877

Sorry, forgot to mention, the Bobo exception message occurs with or without the proxy server. Try http://example.org:8080/manage_workspace and examine the HTTP headers. Same goes with VHM URLs: http://kbui.org:8080/VirtualHostBase/http/kbui.org:8080/VirtualHostRoot/manage_workspace etc. shows the same result, so I don't think it's a proxying/VHM issue.
