"Error: Can't set headers after they are sent" with caronte

[Rush]

Again, I am trying the simplest use case:

var caronte = require('./index.js');
var proxy = caronte.createProxyServer({});
var EventEmitter = require('events').EventEmitter;

require('http').createServer(function(req, res) {
    res.end("TEST");
}).listen(8089)

require('http').createServer(function(req, res) {
  proxy.web(req, res, {
            target: require('url').parse("http://127.0.0.1:8089"),
            ee: new EventEmitter()
  });
}).listen(8081);

Testing ab2 -v 2 -c 1 -n 20 http://127.0.0.1:8081/

> node ./test

http.js:708
    throw new Error('Can\'t set headers after they are sent.');
          ^
Error: Can't set headers after they are sent.
    at ServerResponse.OutgoingMessage.setHeader (http.js:708:11)
    at node-http-proxy/lib/caronte/passes/web-outgoing.js:19:11

Thanks for your support!

I am afraid it is not completely fixed because the request does not finish.
Considering my test:

 # ab2 -v 2 -c 1 -n 1 http://127.0.0.1:8081/

TEST

After that it simply hangs, and sometimes it ends at print 4 and sometimes it prints out TEST as well. The 4 which is content-length should not be there, you write it to socket by accident I think.

ok i'll give it better look tomorrow morning.. thanks for taking the time to report this :)

Still cannot get it work and it seems like the simplest use case. Could you provide any working single file test that would work as a reverse proxy?

I will open a different issue cause I seem to have identified the problem and will specify it there.

[mizuiren]

I have the same problem, "http-proxy": "^1.16.2"
the code :
/**************************/
app.get(/.?\.mp3/, proxyer);

function proxyer(req,res,next){
delete req.headers.host;
return proxy.web(req, res, {target: 'http://fs.open.kugou.com'});
}
/***************************/
It show me log "Error: Can't set headers after they are sent..." while I'm playing mp3 music sometimes.
how to fix it?
