This is not possible, period.

HTTP authentication is possible in an accelerator, but is impossible in an
transparent proxy. HTTP explicitly does not allow authentication in
transparently intercepting proxies and for very good security reasons.

No, not at all. Only that authentication is now available for accelerator
setups without having to resort to undocumented defines.
