lookup
Description:
public abstract string[] lookup (string uri, Cancellable? cancellable = null) throws Error
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[GProxyResolver:password]@]host[GProxyResolver: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.
Parameters:
| this | |
| uri |
a URI representing the destination to connect to |
| cancellable |
a Cancellable, or null |
Returns:
|
A NULL-terminated array of proxy URIs. Must be freed with strfreev. |
