An RMIClientSocketFactory instance associated with a remote object will be downloaded to clients when the remote object's reference is transmitted in an RMI call. This RMIClientSocketFactory will be used to create connections to the remote object for remote method calls.

An RMIClientSocketFactory instance can also be associated with a remote object registry so that clients can use custom socket communication with a remote object registry.

An implementation of this interface should be serializable and should implement Object.equals(java.lang.Object) to return true when passed an instance that represents the same (functionally equivalent) client socket factory, and false otherwise (and it should also implement Object.hashCode() consistently with its Object.equals implementation).
