Stop RPS from asking for <mac>.cfg and common cfg

[jolouis]

Just because the phone requests the different config files does not mean you need to actually serve or provide all of them. For example, it would be fairly easy to setup your server so that it only processes requests for the generic model number files (y0000000000035.cfg) and ignore everything else. Then, whenever the request for that file comes in you do your backend lookup on the MAC info passed by the user agent, and simply pass through (or generate, whatever you want to do) your encrypted config file. Just my two cents anyway.
