How to reduce the number of values in the incoming X-Forwarded-For header in Apache httpd?

Issue

• We use an httpd proxy in front of our application server. Clients access httpd through a number of other balancers and proxies. So by the time the request reaches the backend app server, there are 3 or more values in the X-Forwarded-For header. This causes issues for the application so is there some way the X-Forwarded-For values could be reduced in the request as it passes through the httpd proxy before the app server?

• We need to bypass all the IP address in X-Forwarded-For (except actual client IP address which we want to forward to backend JBoss EAP server), Is there a way to configure this at Apache httpd layer? We do have h/w load balancer in front of Apache httpd server.
