Sure, I can give you an example.
Check out these URL's:
http://mercado.softwarepublico.gov.br/register/
http://teste.softwarepublico.gov.br/mpv/register/
In both of them, the action link for register is /mpv/register. The request processor is going to redirect the request from /mpv/register to /register if you use host-node mapped URL, but the POST will fail because the bug I've mentioned above.
Right now the only way it works is because this patch I've supplied.
