Thanks to Gerald Richter, Vivek Khera, and Ilya Obshadko for suggesting the solution to the X-Forwarded-For problem I was having. After a little bit of experimentation, it would appear that mod_proxy_add_forward module needs to appear before mod_proxy (and therefore be lower down Apache's execution order) in the Apache configuration. Using the ClearModuleList and AddModule directives to specify the required module order solved the problem. In hindsight, this makes a great deal of sense, especially since mod_proxy_add_forward first checks if it's dealing with a proxy request, and this can only be true if mod_proxy has had a chance to execute.
