The 10.5 SDK now supports processing of PAC files, however it's not entirely clear what the correct behavior should be when proxies are down.
For example, say the OS returns 2 proxies: {ProxyA, ProxyB}. ProxyA is down and takes a while for the connection attempt to timeout, but we ultimately discover ProxyB is good, and use it. Should this information be cached, and if so, for how long? For example, say another thread is spawned that tries to make the same connection attempt. Should that second thread already know that ProxyA is down and just go straight to ProxyB (and if so, how long before new threads try connecting with ProxyA again?) or should it *always* retry the full proxy list for every new connection?
Thanks,
Tommy
