Websocket provider support

i see that in the chain configuration the rpcTarget is mandatory but the wsTarget is optional.
I tried to understand when are you using the websocket target, from what i could see it is not in real use.
how can i configure the provider to use websocket, at least for subscription to events (using rpc provider to event subscription causes many requests to be invoked.
