Aha.  Now I begin to see.  I'm not sure I agree, but I see what you're
getting at.

In my particular situation we're using the reverse-proxy to extend our
Apache/mod_perl authentication over a number of "interior" ("inferior"!)
servers, wrapping their authentication with our own.  I don't think this
would be possible without a reverse-proxy within Apache.  At least it
wouldn't be so easy.

Similarily, mod_rewrite's proxy option ([P]) is insanely useful in the
right situation.

That would be useful.

Thanks for the detailed explanation.  I'm new around these parts and I
appreciate the help.
