Simple Express/Connect middleware that dumps a stack trace to console when response-headers are written. Useful to debug "Can't set headers after they are sent" issues.
// include this middleware before any middleware/routes that is suspected of triggering the error
app.use(function(req, res, next) {
res.on('header', function() {
console.trace('HEADERS GOING TO BE WRITTEN');
});
next();
});
