For an apache solution to this problem, you can use mod_rpaf to solve
the issue.  Your proxy servers should be adding a Forwarded-For header
with the IP address of the originating requester.  If you run mod_rpaf
on the servers behind the proxies, and tell it about all your proxy
servers, then it will tell apache what the real originating address
is, and all your apps will see that value.
