I have an interesting problem, we have to reverse proxy incoming web requests to an application that needs to know the end-user's IP address. This is for security not for performance, so there's no need to cache the actuall results. Our current proxy software cannot communicate this information to the backend web server (every requests looks like its coming from the proxy server obviously), and I was wondering if SQUID can do this? It would be like "forwarded_for" for reverse proxy so that there's something in the header the destination web server can read that tells it the requesting client's real IP address. Is there a patch or a well-known config option that has elluded my googling and MARC searching that presents the requestor's IP address to the accelerated server?
TIA Robert
