You could try and roll your own using express. It's not too difficult. I have one you could probably tweak, but it does not handle tokens.
proxy = new httpProxy.RoutingProxy();
// My attempt to use node http-proxy, may or may not work
// Seems to work when trying to proxy to a web site and AGS URLs, so ok
app.all('/proxy', function (req, res) {
var buffer,
url_,
_query,
_query_url,
full_url,
clean_url;
/*
* Apparently need this buffer because
* express turns a POST body response
* into an object.
**/
buffer = httpProxy.buffer(req);
url_ = req.url.split('?')[1];
_query = req.url.split('?')[2];
_query_url = '';
if (typeof _query !== 'undefined') {
_query_url = '?' + _query;
}
full_url = url_ + _query_url;
req.url = full_url;
clean_url = url.parse(url_);
proxy.proxyRequest(req, res, {
host: clean_url.host,
port: 80,
buffer: buffer
});
});
