Do I understand your picture correctly

Internet Users -> Squid Reverse Proxy -> Application Server -> DB

For this no patching of Squid is required, all you need is to modify the
application to use the HTTP_X_FORWARDED_FOR CGI variable rather than
REMOTE_ADDR, with suitable cleanup (there may be more than one address in
X-Forwarded-For if the client request was forwarded via a chain of Squid
proxies).

There is patches to some web servers (Apache 1.3) to automate this, but
quite often this is not required.
