Also, take a look at mod_proxy_add_forward for Apache, and these other resources:

  http://www.zope.org/Members/stephen/ApacheProxyPatch
   http://modules.apache.org/search?id=124

   ftp://ftp.netcetera.dk/pub/apache/mod_proxy_add_forward.c

I believe there is some code in mod_proxy_add_forward to deal with 
getting the client's IP address from chains of proxies.
