Witchcraft stuff does exist to do this, but needs capabilities of the underlying os. Not easy. Far from straight forward. You may check the archives on this. But I recommend a 3 month sabatical first. Basically the remote webserver must check the X-Forwarded-for header which squid includes for each request. If so enabled. I mean, squid must have X-Forwarded 'on'; that should be a default however. M.
