AFAIK there is no system provided mechanism to parse this array. I
recommend that you file a bug requesting one.

Please email the bug number to me so that I can keep an eye on it.
There are a couple of ways around this:
A. Download using CFNetwork instead of curl; CFNetwork will do this
stuff for you automatically.
B. Parse the array yourself by hand.
Of these, option A is probably easier (surprisingly). If Apple's
implementation is anything to go by, the code for option B is
complicated.
As to what to expect in the proxies array, here's the list of things
that Apple's code can handle (in order).
1. a specific host name
2. an IP address, including a subnet (using the standard "/" syntax)
3. a domain name, which bypasses anything 'within' that domain
("apple.com" will cause "www.apple.com" to bypass the proxy)
Finally, Apple's code also always bypasses "localhost", "127.0.0.1",
and "::1" (the IPv6 loopback). It also has an option to bypass any
single-label name.
