    Yes, basically. The difference in terms it is just for (I guess) to
differentiate a proxy (near the user) from a reverse-proxy (near the
server). It is "reverse" because the reference point is the user.

    I have no problem in using "proxy" alone or "reverse-proxy", just
not use something new or not very well defined as "translucent".
