So when a 403 would be generated, you intercept it, do some processing,
and return an appropriate 302 instead.

No, it doesn't.
That directive says "instead of sending a 403, send a 302 for this other
url". What the browser does with that, is up to the browser.

You can try. You may have to take care about url escaping, though.
(You can possibly avoid that if you use something like
.../dhe403.shtml/$request_uri and handle it appropriately on the far
It would seem easier to either proxy_pass or fastcgi_pass to the old
server, in an error_page 403 location on the new server, if you're happy
to have that level of not-just-static involved (and not happy to run
the full php suite on the new server).
That way, the browser would get one redirect to the intended destination
instead of one to an intermediate location first.
