Hello Mike,

>> Please take a look at the SSH proxy feature in PyHoca-GUI and check if
that meets your requirements.
PyHoca-GUI seems to have nothing to do with my wish.

>> Ok, we will investigate what putty is doing and maybe it is quite easy
to immitate that. I am still not sure what there is behind that
technologically.
See http://www.ietf.org/rfc/rfc2616.txt for the CONNECT command in http
and how to deal with proxy servers.

Best regards

Heinrich
