Goal

Some network architectures have edge servers that do not readily provide the actual client IP address for the Web Server. Instead the desired client IP is buried in a custom header.

This document provides a method to extract that client IP address from the custom header so as to provide a mechanism one can use to block specific hosts or networks accessing the Web Server.

When that client IP address is captured the Web Server can send back a 404 error for blocking or some other customized response.
