    proxies working on so-called 'transparent' fashion do not alter
requests and responses, thus acchieving what RFC2616 says. It's true
they alter source IP addresses ... but that is not quoted on RFC2616.

    So it's a matter of interpretation .... the highlighted quote, in my
opinion, does not prohibite a proxy to alter the source IP address, as
long the request and the responde is keep intact.

    That way, the so-called 'transparent' proxy setup is completly
RFC-2616 compliant.
