Unable to forward specific domains through a upstream proxy

Hi all,

I've been struggling for days now trying to get my privoxy to do the
following.   From what I can tell it should be possible (but its not
working)

- Any traffic destined to a specific url (preferably wildcarded) for
example *.google.com to use upstream Socks5 proxy.
- All other traffic to go directly (from the privoxy)

I've tried so many variations now, with the below attempts, but it is only
ever sending everything directly.

#forward-socks5t /*.whatismyipaddress.com socks5://192.168.0.2:1080 .
forward / .
#forward-socks4a / 192.168.0.2:1080 whatismyipaddress.com
#forward-socks5 / obsolete.whatsmyip.org socks5://192.168.0.2:1080
#forward-socks5 obsolete.whatsmyip.org 192.168.0.2:1080 .
#forward-socks5 / http://obsolete.whatsmyip.org/ socks5://192.168.0.2:1080 .
#forward-socks5 / 192.168.0.2:1080 obsolete.whatsmyip.org

forward-socks5 .whatsmyip.org 192.168.0.2:1080 .
forward / .

none seem to be working at all. so i'm baffled

Note that if i tell it to send ALL traffic via the upstream socks proxy,
then it works fine and as expected.   So it seems like it must be the way
that privoxy is processing the config/domains.
Unfortunately the logging isn't working either , despite having the
following in the config, no file gets created

logdir /etc/privoxy
logfile privoxy.log


Can anyone assist in letting me know what the correct syntax is as, despite
reading the manual docs, I am still struggling (and also struggling to find
help on it)

Thanks in advance.
