Cache does not work with images

[JMLX42]

Hello,

I'm trying to use this module to proxy and cache some images coming from external services. It works when I don't set the cache option.

exports.proxy = function(req, res, next)
{
    if (!req.headers['referer'])
        return res.status(400).send();

    var ref_parts = url.parse(req.headers['referer'], true);
    if (ref_parts.host != config.hostname)
        return res.status(400).send();

    return requestProxy({
        cache: redis.createClient(),
        cacheMaxAge: 3600,
        url: req.query.url
    })(req, res, next);
}

The very same code works for other requests/mime-types such as plain HTML or text.

How can we solve this?
