Thanks, this is helpful for me, I know a lot about proxies, I've been stuck behind a really anal (can I say that) one for quite some time and had to learn about how it worked etc so I could work out how to bypass the content filtering methods installed on it. (Business line provided for home use)

Now I'm free of that and I'm looking at installing my own so I can modify traffic and muck around with all that kind of stuff as sort of an educational thing. So achilles looks good for me (Windows user, although starting to get into linux a lot more, mainly for security purposes)

Thanks man.
