Users should be aware of several issues when using standard, common http(s)/socks4(a)/5 proxies (anonymizers that only use http(s)/socks4(a)/5 as an interface are exempt).
- Most problems with these proxies are not caused by Whonix ™.
- Be especially careful with http(s) proxies. Some of them send the "http forwarded for [archive]" header which discloses the IP address. Http(s) proxies that do not send this header are sometimes called "elite" or "anonymous" proxies.
- When using "http forwarded for" http(s) proxies, Tor entry guards and Tor bridges can determine the IP address.
- The unencrypted nature of proxies makes them unsuitable to hide Tor from destination websites. For simple IP logging / IP detection they might work unless they’re http(s) proxies and send the "http forwarded for" header.
