Hi AMG,
I'm not 100% sure, but AFAIK, the RFC allow the request to contain more than one HTTP header with the same name. There is nothing specific to X-Forwarded-For header, so I assume the limitations are the same as other headers.
Moreover, in real life, I regularly face this kind of request containing several X-Forwarded-For headers. That's why I suggested to change the code to take into account this possibility.
