This document defines an HTTP extension header field that allowsproxy components to disclose information lost in the proxyingprocess, for example, the originating IP address of a request or IPaddress of the proxy on the user-agent-facing interface. In a pathof proxying components, this makes it possible to arrange it so thateach subsequent component will have access to, for example, all IPaddresses used in the chain of proxied HTTP requests.

This document also specifies guidelines for a proxy administrator toanonymize the origin of a request.
