Three types are supported: PROXY_TYPE_SOCKS4 (including socks4a), PROXY_TYPE_SOCKS5 and PROXY_TYPE_HTTP addr - The address of the server (IP or DNS). port - The port of the server. Defaults to 1080 for SOCKS servers and 8080 for HTTP proxy servers. rdns - Should DNS queries be performed on the remote side (rather than the local side). The default is True. Note: This has no effect with SOCKS4 servers. username - Username to authenticate with to the server. The default is no authentication. password - Password to authenticate with to the server.
