58 * proxy settings for: |
|
59 * |
|
60 * \list |
|
61 * \o FTP proxy |
|
62 * \o Web Proxy (HTTP) |
|
63 * \o Secure Web Proxy (HTTPS) |
|
64 * \o Streaming Proxy (RTSP) |
|
65 * \o SOCKS Proxy |

66 * \o Gopher Proxy |

67 * \o URL for Automatic Proxy Configuration (PAC scripts) |

68 * \o Bypass list (by default: *.local, 169.254/16) |
|
69 * \endlist |
|
70 * |
