That usually happens when the proxy receives a request that has been
transparently intercepted whilst it isn't set up for transparency.
The proxy will need to know the intended destination address so I guess
you'd need something like WCCP or GRE between the firewall and proxy
server in order to pass the necessary info through. I've not tried
either of those as I prefer telling the browser that it is using a
browser, although I do understand why you are trying to use transparency
in this case.
Hope this Helps,
