* MacOS X has a proxy configuration module in System Preferences (on
* MacOS X 10.5, it's in Network, Advanced), where one can set the

*
* \list
* \o FTP proxy
* \o Web Proxy (HTTP)
* \o Secure Web Proxy (HTTPS)
* \o Streaming Proxy (RTSP)
* \o SOCKS Proxy
* \o Gopher Proxy
* \o URL for Automatic Proxy Configuration (PAC scripts)
* \o Bypass list (by default: *.local, 169.254/16)
* \endlist
*
* The matching configuration can be obtained by calling SCDynamicStoreCopyProxies
* (from <SystemConfiguration/SCDynamicStoreCopySpecific.h>). See
