Hello -- I'm new to openlayers, and I've been running into some issues,
probably because I'm new.  One of the first things I wanted to do was draw a
box, have the server return all the features in the box, and then "do
something" with them.

I thought I'd use something like this:

        var getFeatures = new OpenLayers.Control.GetFeature({
            box: true,
            click: false,
            multiple: true,
            protocol: new OpenLayers.Protocol.HTTP({
                url: '/obj',
                format: new OpenLayers.Format.GeoJSON(),
                params: {
                    limit: 2000
                }
            })
        });

What is the best way to set a custom callback to go off once their is
response data to work with?
