I fell on the same issue and decided to use the session to handle this kind of job.

I didn't want to have an intermediate view...

With the below code, I can redirect to the homepage, which will be rendered with 401 unauthorized code.

app.get('patternForbiddenRoute', (req, res, next) => {
       // previousCode
       if (notForbidden === true) {
           return res.render("a_view");
       }

       req.session.httpCode = 401;

       res.redirect('patternHomeRoute');
});

app.get('patternHomeRoute', (req, res, next) => {
       res.render("my_home_view", {}, (error, html) => {
            // ... handle error code ...

            const httpCode = req.session.httpCode;
            if (httpCode !== undefined) {
                delete req.session.httpCode;
                res.status(httpCode);
            }

            res.send(html);
       }));
});
