I currently have a proxy auto config file setup for OS X 10.9. I can route particular subnets to different socksv5 proxies.
What I am looking to be able to do is add/remove proxied subnets at will. I have thought about dynamic .pac file generation on the http server side of things but there doesn't appear to be any rhyme or reason to when it gets pulled (my http server is running locally as I couldn't get OS X to read it from a file: url).
Does anyone know of how to accomplish this?
