Hi,
I am trying to route requests based on a result I get from redis, but I am
failing miserably.
Consider this pseudo code snippet below:
var proxy = new httpProxy.RoutingProxy();
http.createServer(function (req, res) {
console.log("URL", req.url);
if (req.url) {
var token = req.url.split("/")[1];
// if I leave this code here it works fine
// var target = { host: 'local-01', port: 8024 }
// proxy.proxyRequest(req, res, target);
// now I need to retrieve some routing information
// from redis, so I query redis here
redisClient.get(token, function (err, reply) {
// if I leave this code here the request hangs
var target = { host: 'local-01', port: 8024 }
proxy.proxyRequest(req, res, target);
});
}
}).listen(routerInfo.port, routerInfo.address);
If I call proxy.proxyRequest before querying Redis, it works fine. However,
if I move the code inside Redis callbacks, it fails and the HTTP request
just hangs.
Any idea what's going on here and how to fix it?
Thanks,
-- Felipe.
