As mentioned here last week, the use of "Forwarded" was taken from an
early HTTP/1.1 draft from w3.org. The presence of Forwarded broke
Squid's interaction with at least two sites in particular (novell.com
and readersigest.com). More recent HTTP/1.1 drafts use Via: instead.

The current draft does not provide (anywhere that I can see) for the
original client address to be inserted into the request headers.
Perhaps because might want to use it for some kind of authentication
and it is so simple to fake. The closest thing would be the From:
header.

The HTTP/1.1 draft doesn't seem to have anything to say about 'X-foo'
headers which might be another option.
