SSLSocketFactory
public abstract class SocketFactory extends Object
Socket factories are a simple way to capture a variety of policies related to the sockets being constructed, producing such sockets in a way which does not require special configuration of the code which asks for the sockets:
Factory classes are specified by environment-specific configuration mechanisms. For example, the getDefault method could return a factory that was appropriate for a particular user or applet, and a framework could use a factory customized to its own purposes.
