Virtualvfunc_Checks if resolver can be used on this system. (This is used
internally; g_proxy_resolver_get_default() will only return a proxy
resolver that returns true for this method.)
Virtualvfunc_Looks into the system proxy configuration to determine what proxy,
if any, to use to connect to uri. The returned proxy URIs are of
the form <protocol>://[user[:password]@]host[:port] or
direct://, where <protocol> could be http, rtsp, socks
or other proxying protocol.
If you don't know what network protocol is being used on the
socket, you should use none as the URI protocol.
In this case, the resolver might still return a generic proxy type
(such as SOCKS), but would not return protocol-specific proxy types
(such as http).
direct:// is used when no proxy is needed.
Direct connection should not be attempted unless it is part of the
returned array of proxies.
