 * This method returns a Socket.  Properties control the use of
 * socket factories and other socket characteristics.  The properties
 * used are: <p>//from  w  ww. jav a  2 s . co m

 * <li> <i>prefix</i>.socketFactory.fallback

 * </ul> <p>
 * If the socketFactory.class property isn't set, the socket
 * returned is an instance of java.net.Socket connected to the
 * given host and port. If the socketFactory.class property is set,
 * it is expected to contain a fully qualified classname of a
 * javax.net.SocketFactory subclass.  In this case, the class is
 * dynamically instantiated and a socket created by that
 * SocketFactory is returned. <p>
 *
 * If the socketFactory.fallback property is set to false, don't
 * fall back to using regular sockets if the socket factory fails. <p>
 *
 * The socketFactory.port specifies a port to use when connecting
 * through the socket factory.  If unset, the port argument will be
 * used.  <p>
 *
 * If the connectiontimeout property is set, we use a separate thread
 * to make the connection so that we can timeout that connection attempt.
 * <p>
 *
 * If the timeout property is set, it is used to set the socket timeout.
 * <p>
 *
 * If the localaddress property is set, it's used as the local address
 * to bind to.  If the localport property is also set, it's used as the
 * local port number to bind to.
 *
 * @param host The host to connect to
 * @param port The port to connect to at the host
 * @param props Properties object containing socket properties
 * @param prefix Property name prefix, e.g., "mail.imap"
