I looked at junkbuster too but the code was too ropey and it failed too
often for me to trust it, not to mention the issue above. This evening
I've just hacked up a general purpose redirector which I'll be submitting
to the 'contrib' software just as soon as I've made it into publishable
quality code (ie get rid of statically sized arrays, pre-compile the
regexps once, the usual stuff...)

Here's a sample input file, and you can see how you can use it for
what you want; the redirector knows the client IP (unless of course
you come from another proxy in which case you're out of luck again).
