-__Note__: When you forward http requests to io routes, `req.io.respond(data)` will call `res.json(data)` on the actual http request.  This  makes sense because http routes require a response, and the `respond` method is supposed to be a response for the given request.

 Also, depending on the sophistication needed between a socket request and a web request, you might consider writing your own custom middleware layer and overriding `req.io.route` for your web requests.
