Ocamlnet 4 Reference Manual : Uq_socks5.proxy_client

# Class Uq_socks5.proxy_client

    class proxy_client : Uq_engines.connect_address -> object .. end

The object created by `new proxy_client addr` can be passed as `proxy` to the `Uq_engines.connector`, `Uq_engines.listener`, and `Uq_engines.datagram_provider` functions to use the SOCKS proxy for connections, servers, and datagram socket, respectively.

The SOCKS client supports the following methods:

- `connect`: Only TCP connections are supported (UDP could be made working - TODO)
- `listen`: This works (only) for TCP sockets, too
- `create_datagram_socket`: Creates unconnected datagram sockets that can be sent and received with object methods

Note that socket addresses are resolved by the proxy host; this applies to both ``Sock_inet` and ``Sock_inet_byname`. For the latter this means that name resolution is done by the proxy.

The nature of SOCKS restricts the functionality:

- ``Sock_unix` addresses are not supported (i.e. you cannot connect to a Unix domain socket on the proxy host)
- Listening server sockets can only accept one connection; after that they are "dead" and must be shut down first. The method `multiple_connections` is `false` because of this.
- Further restrictions can be enforced by the SOCKS proxy and its configuration.
