My sometimes jaded view is that the proxy rewrites the traffic to
conform to whatever the proxy writer wrote. Hopefully, that matches up
with some standard protocol to _provide_ the security. I.E. You get the
security from the proxy writer having rewritten your traffic. It's doing
*something,* true, but it's not "checking" anything. It's just not
re-writing any *bad* stuff.
