OK, if I will enable mod_rewrite to do the same Destination rewriting and will
apply 'all the transformations done to the original request URL' -- will it have
a chance to be committed? To tell the truth, just now I have no idea what are
those 'all transformations' but will try to understand. May be you will be so
kind to point me to the relevant code locations?

And if we will turn this into the documentation issue, I will vote that
mod_dav's documentation should note that the 'Destination' should be rewritten
if we're living with the proxy. It is not obvious for the administrator when the
proxied DAV is refusing to to PUT and MOVE.
