Snort on web servers behind reverse proxies

Hi First of all I did some research and couldn't find anything about this, so no flames please :-) Here is the story. We have some reverse proxies/application accelerators/etc. (let's call them reverse proxies for now) in front of our web site. We don't control these reverse proxies and I am not sure if the provider has any IDS capabilities on those. I have snort (2.8.0.2) installed on the actual web servers but the only thing that I see in the alerts is the IP addresses of the reverse proxies, which is normal. Now, the reverse proxies, in their http requests to the web servers, they add 2 entries in the headers: X-Forwarded-For: <origin's IP address> and True-Client-IP: <origin's IP address>. Is it a way to modify the rules to alert using any of these IP addresses instead of the IP address(es) of the reverse proxies ? Any help/idea would be appreciated.
