There is no caching of the proxy list, since the PAC file could change
and the proxy server's status could change as well.

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,
