"Because the proxy is to be told where to connect and receives a
direct secure handshake."

is that necessary even if stunnel is told to not verify the connections?
''If no verify argument is given, then stunnel will ignore any
certificates offered and will allow all connections.''
and i gave no verify anywhere.

"Privoxy is useless with encrypted data"
i tried it again but with all 'debug' levels set in privoxy, and its
true that after a while, these errors are written:
"Invalid request" 400 0
Error: Invalid header received from
Writing: HTTP/1.0 400 Invalid header received from client

is this because of TLS encryption? does this mean privoxy cant even
simply forward TLS requests?
if so, can anyone tell me a proxy that can, and preferably doesnt do
anything else? and works on windows?
