// To use a SOCKS4 or SOCKS5 proxy, simply set the following
// properties prior to calling Connect.  The connection may be SSL/TLS or 
// non-secure - both will work with a SOCKS proxy.

// IP address:

// of the SOCKS proxy server:

// Note: SOCKS4 servers only support usernames without passwords.
// SOCKS5 servers support full login/password authentication.
