At a fundamental level, no, because the assertions issued to any form of proxy are unusable by and should never be given to whatever the back-end is, and our software is not going to keep supporting assertion access. If you just mean "consume assertion and pass data along to back-end", that's what our SP literally does.

Apache commands or the RequestMap, as documented.
