Does anyone know if this variable (HTTP_X_FORWARD or the like) can be
instantiated on MS Proxy Server?
I can find nothing on it. I use reverse proxy publication to re-route
external requests to an internal web server, and would love to collect the
actual IP address from the internal logs as opposed to trying to coordinate
the external log (with the real ip address) and the internal log (that has
the proxy server address as the REMOTE_ADDR).
Anyone? Bueller? Anyone?
