Catching the finish event of a response?

[trusktr]

How would I execute something after Locomotive sends a response? In one of my controller#methods I've done

this.res.on("finish", function() {
    console.log(" -- Reponse sent! "); // Never happens.
});

but I never see the message logged to the console. Is there some way to do this in Locomotive?

I'm trying to keep track of some data across a few requests, then delete the data after a certain request is made, and the response to that request relies on the data, so I'm trying to clean up the data after the response to the final request is sent.

Use an after filter.

@drudge How does that guarantee the response is finished?
